A $0.0020 \text{ m}$ aqueous solution of an ionic compound $\text{Co(NH}_3)_5(\text{NO}_2)\text{Cl}$ freezes at $-0.00732^\circ\text{C}$. Number of moles of ions which $1 \text{ mol}$ of ionic compound produces on being dissolved in water will be ($K_f = 1.86^\circ\text{C m}^{-1}$)
Consider the following reaction. The structure of the major reaction intermediate formed in the above reaction is-
$p_A$ and $p_B$ are the vapour pressures of pure liquid components A and B, respectively, of an ideal binary solution. If $x_A$ represents the mole fraction of component A, the total pressure of the solution will be:

Among the following, the reaction that proceeds through an electrophilic substitution, is:
A diamagnetic lanthanoid ion among the following is : (At. numbers: $\text{Ce} = 58$, $\text{Sm} = 62$, $\text{Eu} = 63$, $\text{Yb} = 70$)
The number of hydrogen bonded water molecules(s) associated with CuSO₄·5H₂O is:
The reason for a greater range of oxidation states in actinoids is attributed to:
The freezing point depression constant for water is $1.86^\circ\text{C m}^{-1}$. If $5.00 \text{ g Na}_2\text{SO}_4$ is dissolved in $45.0 \text{ g H}_2\text{O}$, the freezing point is changed by $-3.82^\circ\text{C}$. Calculate the van't Hoff factor for $\text{Na}_2\text{SO}_4$.
Choose the correct statement:
The molecular formula of a commercial resin used for exchanging ions in water softening is $C_8H_7SO_3Na$ (Mol. Wt. 206). The maximum uptake of $Ca^{2+}$ ions by the resin when expressed in mole per gram resin is based on the reaction: $$ 2C_8H_7SO_3Na + Ca^{2+} \rightarrow (C_8H_7SO_3)_2Ca + 2Na^+ $$
The freezing point depression constant for water is $1.86 ^\circ\text{C m}^{-1}$. If $5.00 \text{ g}$ $Na_2SO_4$ is dissolved in $45.0 \text{ g}$ $H_2O$, the freezing point is changed by $-3.82 ^\circ\text{C}$. The Van’t Hoff factor for $Na_2SO_4$ is:
The mixture that shows positive deviation from Raoult's law is:
