Detailed Solution

a) Solubility product depends on the formula type of the salt [so false]

b) $\large BaS{O_4}\left( s \right) \rightleftharpoons BaS{O_4}\left( {aq} \right)\xrightarrow{{}}B{a^{ + 2}}\left( {aq} \right) + SO_4^{ - 2}\left( {aq} \right)$

In dil.H₂SO₄, $\large SO_4^{ - 2}$ ions will be present. As a result of common ion effect solubility of BaSO₄ in dil H₂SO₄ will be suppressed. [so true]

c) $\large Pb{I_2}\left( s \right) \rightleftharpoons Pb{I_2}\left( {aq} \right)\xrightarrow{{}}P{b^{ + 2}}\left( {aq} \right) + 2{I^ - }\left( {aq} \right)$

KI is a strong electrolyte and so will furnish a high concentration of I^- ions. As a result of common ion effect, solubility of PbI₂ will be suppressed. [so true]

d) $\large AgCl\left( s \right) \rightleftharpoons AgCl\left( {aq} \right)\xrightarrow{{}}A{g^ + }\left( {aq} \right) + C{l^ - }\left( {aq} \right)$
