a) Why do acids not show acidic behavior in the absence of water?

b) Name the substance which on treatment with chlorine yields bleaching powder.​

Answer 1

a) Why do acids not show acidic behavior in the absence of water?

---- The acidic behaviour of acid is due to the presence of hydrogen ions. The acids will not show its acidic behaviour in the absence of water, this is because acids do not dissociate to produce H+ (aq) ions in the absence of water.

b) Name the substance which on treatment with chlorine yields bleaching powder.​

---- Calcium hydroxide

Answer 2

Answer:

1)the acidic behaviour of acid is due to the presence of hydrogen ions. the acids will not show it's acidic behaviour in the absence of water, this is because acids do not dissociate to produce H+(aq) ions in the absence of water.

2) calcium hydroxide [Ca(OH)2], on the treatment with chlorine Cl2 , yields bleaching powder.
