Which of the following sulphides has the lowest solubility product
$FeS$
$MnS$
$PbS$
$ZnS$
(c) Sulphides of Group$-II$ radicals have low solubility product.
Which of the following is least soluble in water
The solubility product of lead bromide is $8\times10^{-5}$. If the salt is $80\%$ dissociated in saturated solution, find the solubility of the salt
A mixture of $100\, m\, mol$ of $Ca(OH)_2$ and $2\, g$ of sodium sulphate was dissolved in water and the volume was made upto $100\, mL$. The mass of calcium sulphate formed and the concentration of $OH^-$ in resulting solution, respectively are
(Molar mass of $Ca(OH)_2, Na_2SO_4$ and $CaSO_4$ are $74, 143$ and $136\, g\, mol^{-1}$ respectively; $K_{sp}$ of $Ca(OH)_2$ is $5.5 \times 10^{-6}$)
$K_{sp}$ for $BaSO_4$ at $25\,^oC$ is $1.1 \times 10^{-10}$. To make the new solubility equal to $1.1 \times 10^{-8}$, it is necessary to use the solution of $Na_2SO_4$ of the following concentration….$M$
Solubility of $BaF_2$ in a solution of $Ba(NO_3)_2$ will be represented by the concentration term?
