Equilibrium Question 213
Question: $ K _{sp} $ for sodium chloride is $ 36mol^{2}/litre^{2}. $ The solubility of sodium chloride is [BHU 1981]
Options:
A) $ \frac{1}{36} $
B) $ \frac{1}{6} $
C) 6
D) 3600
Show Answer
Answer:
Correct Answer: C
Solution:
NaCl ⇌ $ \begin{matrix} N{a^{+}}, & + & ,C{l^{-}} \\ S, & {} & ,S \\ \end{matrix} $
$ K _{sp}=S^{2} $ , $ S=\sqrt{K _{sp}}=\sqrt{36}=6 $ .
