For each of the salts on the left, match the salts on the right that can be compared directly, using ksp values, to estimate solubilities.(if more than one salt on the right can be directly compared, include all the relevant salts by writing your answer as a string of characters without punctuation, e. g, abc.)1. iron(iii) sulfide a. caco32. manganese(ii) carbonate b. ba3(po4)2c. zn3(po4)2d. co(oh)2write the expression for k in terms of the solubility, s, for each salt, when dissolved in water. iron(iii) sulfide manganese(ii) carbonateksp =ksp =note: multiply out any number and put it first in the ksp expression. combine all exponents for s.
