A) \[1+\alpha \]
B) \[1-\alpha \]
C) \[1+2\alpha \]
D) \[1-2\alpha \]
Correct Answer: C
Solution :
\[N{{a}_{2}}S{{O}_{4}}\] ? \[\] \[2N{{a}^{+}}\,\,\,\,\,+\,\,\,\,\,\,\,SO_{4}^{2-}\] Mol. before diss. 1 0 0 Mol. after diss \[1-\alpha \] \[2\alpha \] \[1\alpha \] \[i=\frac{\text{Exp}\text{.C}\text{.P}\text{.}}{\text{Normal}\,\text{C}\text{.P}\text{.}}=1-\alpha +2\alpha +\alpha =1+2\alpha \]
