Question

which comound is more soluble in an acidic solution than in a neutral solution.
1)PBr2
2) CuCl
3) Agi
4) BaF2
​

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
