Question

As a result of dissolution of NaCl in water, the entropy (A) increases (B) decreases (C) remains unchanged (D) becomes zero

NaCl(aq) arrow NA+(aq) + Cl-(aq) The ions that were held together in crystalline solid are now moving in all possible directions. Thus entropy increases.

Q. As a result of dissolution of $N a Cl$ in water, the entropy

increases

decreases

remains unchanged

becomes zero

$N a C l_{(a q)} \to N A_{(a q)}^{+} + C l_{(a q)}^{-}$
