Question

Which compound is more soluble in an acidic solution than in a neutral solution? a) PbBr2 b) CuCl c) AgI d) BaF2

Answer 1

Answer:

d) BaF2

Explanation:

The compound which is more soluble in an acidic solution than in a neutral solution is shown below:-

First we will compare acidic with Neutral

$acidic \rightarrow H+ ions$

So,

$PbBr2 \rightarrow Pb+2 + 2Br-$

$BaF2 \rightarrow Ba+2 + 2F-$

$AgI \rightarrow Ag+ + I-$

$CuCl \rightarrow Cu+ + Cl-$

Now, when we add H+ ions, so it will be

$BaF2 \rightarrow Ba+2 + 2F-$

$F- + H2O HF + OH-$

Then it will reduces F-, as BaF2 begin to form more aqueous ions, so, it will rises the solubility
