Answer #1

Solution :-

When acid is added to water then it dissociates to form the hydronium ion and carbonate anions

following is the reaction equation for he reaction. Carbonic acid is diprotic acid therefore it can show 2 dissociation equations

H2CO3(aq) + H2O(l) ------- > H3O^+(aq)   + HCO3^-(aq)                     first dissociation

HCO3^-(aq) + H2O(l) ------ > H3O^+(aq)   + CO3^2-(aq)                     second dissociation

Carbonic acid (H2CO3) is a diprotic acid (Ka1 = 4.5 x 10-7 and Ka2 = 4.7 x 10-11) and plays a role in blood chemistry, cave formation, and ocean acidification. Calculate the equilibrium values of [H3O+], [HCO3-], [H2CO3], and [CO32-] and find the pH of a 0.075 M H2CO3 solution.

The interaction between carbon dioxide and water results in formation of carbonic acid, H2CO3, which lowers the pH of water through the reactions H2CO3(aq)+H2O(l) <---> HCO3-(aq) + H3O+(aq) Ka1= 4.3*10^-7 HCO3-(aq) +H2O(l) <---> CO3 2- (aq) + H3O+ (aq) Ka2=5.6*10^-11 This dissocociation causes "normal" rainwater to have a pH of approximately 5.7. However, H3O+(aq) can also come from other sources, particularly from acids resulting from interactions of water with industrial pollutants. Scientists studying a particular lake found that its pH...
