Question

This single equilibrium equation applies to different phenomena described in this or the preceding chapter. CH_3 COOH + H_2O right harpoon over left harpoon H_3O^+ + CH_3 COO^- Of these four phenomena, ionization of pure acid, common-ion effect, buffer solution, and hydrolysis, indicate which occurs if (a) [H_3O^+] and [CH_3 COOH] are high, but CH_3 COO^-] is very low. (b) [CH_3 COO^-] is high, but [CH_3 COOH] and [H_3O^+] are very low (c) [CH_3 COOH] is high, but [H_3O^+] and [CH_3 COO^-] are low (d) [CH_3 COOH] and [CH_3 COO^-] are high, but [H_3O] is low.

Explanation / Answer

This process is IONIZATION of pure acid

the pure acid is in water

therefore

it donateds H+ to H2O so it forms H3O+

The acid will form its conjugate base

in this case

[H3O+] = [CH3COO-] < [CH3COOH] because it is weak acid

th ebest answer is

C
