Question

Pbbr2,cucl,agi,baf2 which is more soluble in acidic solution than in neutral solution

Answer 1

Answer:

Acidic Vs. Neutral

acidic---->H+ ions

then

PbBr2---->Pb+2+2Br-

BaF2------>Ba+2+2F-

Agl------->Ag+ +l-

CuCl----->Cu+ + Cl-

if we add H+ ions then

BaF2---->Ba+2 +2F-

F-H2O<->HF + OH-

then F decreases

BaF2 start to form more aqueous ions so increases solubility

Answer 2

$BaF_{2}$ is more soluble in acidic solution than in neutral solution.

Explanation:

An acidic solution is defined as the one which contains hydrogen ions ($H^{+}$) in it. And, more is the ionic character present in a compound more readily it will dissociate into ions.

Out of the given species $BaF_{2}$ is the most acidic as fluorine is highly electronegative in nature. So, there will be a partial positive charge on barium and a partial negative charge on fluorine.

Hence, $BaF_{2}$ is more soluble in acidic solution.
