Question

Which of the following will give a neutral pH solution when dissolved in water?

• A. $NaOH$
• B. $CsCl$
• C. $HBr$
• D. $C{H}_{3}COOH$
• E. $O_2$

Answer 1

The correct option is B $CsCl$

CsCl will give a neutral pH solution when dissolved in water.
$NaOH$ is a strong base. It completely dissociates in solution into sodium ions and hydroxide ions.
$NaOH\to N{a}^{+}+O{H}^{-}$
HBr is a strong acid. Acetic acid $C{H}_{3}COOH$ is also a weak acid. Oxygen, $O_2$ is a neutral compound.
