What are Colligative properties ?

Actually the word co-ligative itself reveals that (“co” means each other and “ligative” means related) These are the properties which are related to each other. The colligative properties are those properties that depend on the number of solute particles in a solution or a mixture. “These properties don’t depend upon the nature of particles “.Continue reading “What are Colligative properties ?”

Why H3PO3 is a diprotic acid? Give reason with structure .

Meaning of diprotic acid is that , it can loose two hydronium ions (H+) . For finding how many H+ ions it can give , we have to see its structure. Here it have only two hydroxyl groups that is -OH groups, and the hydrogen atoms joined to these only are ionisable. So only theseContinue reading “Why H3PO3 is a diprotic acid? Give reason with structure .”


What are azetopes? Azeotropes are the constent boiling mixtures or solutions. it means that these mixtures can not be separated by simple distillation or boiling , because they will have the same composition of mixture even in the vapour state. for example as in case of mixture of nitric acid and water, the highest attainedContinue reading “Azeotropes”

what is valency ? how to calculate it?

Valency :- “It is the combining capacity of an atom”. it also indicates the number of electrons that can be gained , lost or shared . It decides that how many bonds can be formed, it gives the idea of molecule formation and the type of bond formed. calculation of valency is a simple taskContinue reading “what is valency ? how to calculate it?”
