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

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

So,

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

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

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current
