$MgSO_4$

Vedclass · Answer

(D) The Van't Hoff factor $i$ represents the number of particles a solute dissociates into in a solution. For $K_2SO_4$,$i = 3$ $(2K^+ + SO_4^{2-})$. For $NaHSO_4$,$i = 2$ ($Na^+ + H^+ + SO_4^{2-}$ is incorrect,it dissociates as $Na^+ + HSO_4^-$ in dilute solution,so $i = 2$). For Sugar,$i = 1$ (non-electrolyte). For $MgSO_4$,$i = 2$ $(Mg^{2+} + SO_4^{2-})$. Both $NaHSO_4$ and $MgSO_4$ have $i = 2$. However,$MgSO_4$ is the standard example for a $1:1$ electrolyte dissociating into $2$ ions.

Which of the following compounds has a Van't Hoff factor $i$ equal to $2$ for a dilute solution?
