(d) why does the h3o concentration have more influence on the precipitation of the salt of a weak acid, such as cac2o4(s), than on the precipitation of the salt of a strong acid, such as agcl(s) or caso4(s)?

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.

the answer is b. dilution
