 What is strong, moderate and week electrolytes in physical chemistry ?


 

        Electrolytes are classified as strong electrolytes, weak electrolytes and moderate electrolytes.

       Strong electrolytes : These are those substances which are almost completely ionizes or dissociates into in the aqueous solution or in the molten state and hence conduct electricity to a large extent. For example, strong acids (HCl, HNO3, H2S04 etc.), strong bases (NaOH and KOH etc.) and most of the inorganic salts in fused state, (NaCl, NH4Cl etc.).

        Weak electrolytes : These are those substances which ionizes to a small extent into ions in solution phase and hence conduct electricity to a small extent. For example, weak acids such as CH3COOH,HCN, H2CO3 etc. and weak bases such as NH4OH, Ca(OH)) etc.

         Moderate Electrolytes : These are those substances which exhibit an intermediate behaviour between strong and weak electrolytes. For example, trichloroacetic acid (ClCHCOOH) etc.

        Non-electrolytes : Substances like sugar, urea, alcohol, glycerine etc. which do not conduct electricity (even in solution) are called non-electrolytes. These substances do not give ions when dissolved in solve or in molten state. Hence, they are unable to conduct electricity.

What is thyroid eye disease ? thyroid associated ophthalmopathy (TAO), thyroid orbitopathy, Graves’ orbitopathy or Graves’ ophthalmopathy (GO) ? Thyroid eye disease (TED) is an eye condition that causes the muscles and soft tissues in and around your eye socket to swell. It usually happens when you have a problem with your thyroid gland. It may also be called thyroid associated ophthalmopathy (TAO), thyroid orbitopathy, Graves’ orbitopathy or Graves’ ophthalmopathy (GO). The ocular manifestation of thyroid eye diseases are manifolds. They may be present as thyrotoxicosis, lid retrac- tion, soft tissue involvement, proptosis and optic neuropathy.         The Thyrotoxicosis (Graves dis- eases)         Usually present with 3rd to 4thdecades of life, women are mostly effected than the men with involvement organ specific autoimmune disorders. Thyroid eye diseases may be present as a simple eye disco...

Who discovered proton and neutron ? How to discovered proton and neutron ? What is canal ray? What is anode ray ? | Inorganic chemistry | chemistry.

              Inorganic Chemistry |Chemistry   Discovery of Protons and Neutrons           Electrical discharge carried out in the modified cathode ray tube led to the discovery of canal rays and anode rays carrying positively charged particles. The characteristics of these positively charged particles are listed below.      (i) Unlike cathode rays, mass of positively charged particles depends upon the nature of gas present in the cathode ray tube. These are simply the positively charged gaseous ions.       (ii) The charge to mass ratio of the particles depends on the gas from which these originate.       (iii) Some of the positively charged particles carry a multiple of the fundamental unit of electrical charge.      (iv) The behaviour of these particles in the magnetic or electrical field is opposite to that observed for electron or cathode rays. ...

Who discovered electron ? How to discovered electron ? What is cathode ray discharge tube ? What is cathode ray and cathode ray particles ? | Inorganic chemistry | Chemistry.

                Inorganic chemistry | Chemistry   Discovery of Electron                   In 1830, Michael Faraday showed that if electricity is passed through a solution of an electrolyte, chemical reactions occurred at the electrodes, which resulted in the liberation and deposition of matter at the electrodes. These results suggested the particulate nature of electricity.           In mid 1850s many scientists mainly Faraday began to study electrical discharge in partially evacuated tubes, known as cathode ray discharge tubes . A cathode ray tube is made of glass containing two thin pieces of metal, called electrodes, sealed in it. The electrical discharge through the gases could be observed only at very low pressures and at very high voltages. The pressure of different gases could be adjusted by evacuation of the glass tubes. When sufficiently high vo...

Monetary Policy of Malaysia

-
  Monetary Policy in Malaysia             Prior to the 1997 Asian Financial Crisis, the Malaysian ringgit was an internationalized currency, which was freely traded around the world. Just before the crisis, the Ringgit was traded RM2.50 at the dollar. Due to speculative activities, the Ringgit fell as much as RM5.00 to the dollar in matter of weeks. Bank Negara Malaysia, the nation's central banks decided to impose capital controls to prevent the outflow of the Ringgit in the open market. The Ringgit is not traded internationally, a traveller needs to declare to the central bank if taking out more than RM10,000 out of the country and the Ringgit itself was pegged at RM3.80 to the US dollar. The fixed change rate was abandoned to floating exchange rate in July 2005, hours after People's Republic of China announced the same move. At this point, the Ringgit is still not internationalized. The Ringgit continue to strengthen to 3.18 to the dollar in March 2...

Architecture and sculptures of Assam

Architecture and Sculpture Assam has a rich heritage of architecture and sculpture from ancient times. The manuscripts or inscriptions, remains of temples or shrines and old mementoes remind us the rich legacy of these art forms. The stone gate of Do-parbotia at Sonitpur is the example of oldest architecture discoveree till now. We find the es- sence of early Gupta era architecture in this gate.                         Umachal Silalipi discovered on Nilachal hills at Guwahati is the oldest inscription found till date. Many palaces or me- mentoes were built in ancient Kamrup under the auspices of various royal dynasties. Most of them got ruined with the passage of time. Among them the Siddheswari temple at Kamrup district is worthy of mention. The influence of South Indian architecture is seen in this temple.          After that...

Preface: I had a rare chance to go to Kuwait and stay there for about one and half year. This chance came to me and our family as my father was given an overseas assignment in Kuwait during the period 2008-2010 Now through this article I am going to share my experience of Kuwait which I will cherish all my life.  Geographical and General features of Kuwait:  Kuwait is a small country located in the Middle Easton bank of the Persian Gulf and between Iraq and Saudi Arabia. It is a desert country with intensely hot summers and short, cool winters, The terrain varies minimally, between flat, sandy and slightly undulating desert plains. The area of the country is only 17800 square KM. However there are few oases where vegetables, lakhs of date trees etc are grown and poultry are bred. Kuwait is an Islamic sovereign country run by elected parliament and the King. Now women can also take part in clection process and contest in the election process.  Population Pattern:  Kuw...

Get a healthy heart Follow these mantras to keep your heart healthy- There’s no denying the fact that heart health is of utmost importance. And before we land up at the doctor’s chamber, it is essential that we take care of ourselves in all the ways possible. Some of the most basic steps we can take in this regard are: Exercise regularly Adults need at least 30 minutes of exercise five or more days a week for a healthy heart. Try to get at least 30 minutes of exercise daily and break it up, if you like. You should get your heart rate up so that you are somewhat breathless, but can still carry on a conversation. All kinds of exercises are important, from strength training and aerobics, to flexibility and stretching. Food rules  1) Limit bad fat : Eat less saturated fat. You can reduce your risk of heart disease by half. Start by switching to low-fat meat and dairy, and change to healthier fats like olive and canola oils.  2) Cut the salt : Cook with less salt, limit proce...
