Question

$HCl$ is completely neutralised by $NaOH$ solution. The resulting solution contains the following species

• A. $Na^{+},Cl^{-},H_{3}O^{+}$
• B. $Na^{+},Cl^{-},H_{2}O$
• C. $Na^{+},Cl^{-},OH^{-}$
• D. $H^{+},H_{3}O^{+}$

Answer 1

Answer: (B)

$Na^{+},Cl^{-},H_{2}O$

Answer 2

$HCl$ is completely neutralised by $NaOH$ solution gives $NaCl$ (salt). $HCl + NaOH\,NaCl + H _{2} O\,HClH ^{+}+ Cl ^{-} NaOH\,Na ^{+}+ OH ^{-}$ $H ^{+}+ OH ^{-} \rightarrow H _{2} O$ Hence, the resulting solution contains $Na ^{+}, Cl ^{-}$and $H _{2} O$.
