What would be the value of van’t Hoff factor for a dilute solution of $\text{K}_2\text{SO}_4$ in water. Assume that $\text{K}_2\text{SO}_4$ is completely ionised.
Answer
Answer
Official answer key$\mathrm{K_2SO_4 \rightarrow 2K^+ + SO_4^{2-}}$, so the van't Hoff factor $i = 3$ (complete ionisation).
Final answer: 3
