Question

WHY DO ACIDS NOT SHOW ACIDIC BEHAVIOUR INABSENCE OF WATER ? 2] WHAT HAPPENS WHEN EXCESS OF CARBON DIOXIDE IS PASSED THROUGH LIME WATER ?

Answer 1

A. according to the Arrhenius theory, the acids are hydrolyzed to produce only hydrogen ion as cation. on absence of water acids could not get hydrolyzed to produce hydrogen cation/hydroxonium ion, which is the cause of acidity .

B. when carbon di oxide was passed through lime water(calcium hydroxide) the lime water reacts with the carbon di oxide to form calcium carbonate, which is insoluble in water, makes the lime water opaque. But when excess carbon di oxide was passed the calcium carbonate further reacts with the carbon di oxide and water to form water soluble calcium bi carbonate and as a result the lime water again turns clear,.
