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

d) BaF2

Step-by-step 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
