When concentrated acid is diluted, water should not be added to the acid. Why?

How concentrated sulphuric acid is diluted in the laboratory?

What happens when Boric acid is added to water

How many grams of concentrated nitric acid solution should be used to prepare 250 mL of 2.0M HNO_3 ? The concentrated acid is 70% HNO_3 (w/w).

How many grams of concentrated nitric acid solution should be used to prepare 250mL of 2.0M HNO_(3) ? The concentrated acid is 70% HNO_(3) (w/w)

BCl_3 is a good Lewis acid. Why?

Formic acid is obtained when:

Hot concentrated sulphuric acid is a strong oxidising agent. Why?

How do you account for the following observations? a) Though alkaline potassium permanganate and acidic potassium permanganate both are used as oxidants, yet in the manufacture of benzoic acid from toluene we use alcoholic potassium permanganate as an oxidant. Why? Write a balanced redox equation for the reaction. b) When concentrated- sulphuric acid is added to an inorganic mixture containing chloride, we get colourless pungent smelling gas 'HCl', but if the mixture contains bromide, then we get red vapours of bromine. Why?

When some sodium acetate is added to a solution of acetic acid, the concentration of unionised acetic acid increases. What happens to the value of solubility and solubility product when HCl is passed through an AgCl solution?

Why is concentrated sulphuric acid not used as a drying agent in the preparation of ammonia?
