When sodium acetate is added to an acetic acid solution,the $pH$ of the solution will . . . . . . .

In the precipitation of the iron group in qualitative analysis,ammonium chloride is added before adding ammonium hydroxide to:

What is the concentration of acetate ions in a solution containing $0.1 \, M$ acetic acid and $1.0 \, M \, HCl$? $[K_a = 2 \times 10^{-5}]$

Assertion : In the third group of qualitative analysis,$NH_4Cl$ is added to $NH_4OH$ medium.
Reason : This is to convert the ions of group into their respective chlorides.

In the presence of $HCl$,$H_2S$ results in the precipitation of Group-$2$ elements but not Group-$4$ elements during qualitative analysis. It is due to

Calculate the solubility of $AgCl$ in a $0.1 \ M \ NaCl$ solution. (Given: $K_{sp}$ of $AgCl = 1.6 \times 10^{-10}$)
