How many grams of water are required to dissolve $4 \ g$ of sodium sulfate at $323 \ K$? The solubility of sodium sulfate at this temperature is $16\%$.

$1 \ g$ of silver gets distributed between $10 \ cm^{3}$ of molten zinc and $100 \ cm^{3}$ of molten lead at $800^{\circ} C$. The percentage of silver still left in the lead layer is approximately

Explain the hydration of sodium chloride.

What happens when a saturated solution of sugar is heated?

$A$ company dissolves '$X$' amount of $CO_{2}$ at $298 \ K$ in $1 \ L$ of water to prepare soda water. $X = ........ \ \times 10^{-3} \ g$ (nearest integer).
(Given: partial pressure of $CO_{2}$ at $298 \ K = 0.835 \ bar$.
Henry's law constant for $CO_{2}$ at $298 \ K = 1.67 \ kbar$.
Atomic mass of $H$,$C$ and $O$ is $1$,$12$ and $16 \ g \ mol^{-1}$,respectively.)

Which of the following statement$(s)$ is/are correct regarding the solubility of solid $I_2$?
