Answer:
See explanation
Explanation:
When we are comparing the effect of H3O^+ on the precipitation of a salt of a weak acid such as CaC2O4(s) and that of a strong acid such as AgCl(s) or CaSO4(s), we discover that H3O^+ has more effect on the precipitation of the salt of a weak acid.
This is because, anions of the weak acid combine with H^+ from H3O^+ thereby decreasing the concentration of the anion of the salt of the weak acid and increasing the solubility of the precipitate.
