Answer
Explanation:
Step1: Recall salt - formation rule
A neutral salt is formed when a strong acid reacts with a strong base.
Step2: Analyze each option
- For $2NaOH + H_2SO_4$: $NaOH$ is a strong base and $H_2SO_4$ is a strong acid. The reaction is $2NaOH + H_2SO_4=Na_2SO_4 + 2H_2O$, and $Na_2SO_4$ is a neutral salt.
- For $NaOH + HCN$: $NaOH$ is a strong base but $HCN$ is a weak acid. The salt formed will be basic.
- For $KOH + HF$: $KOH$ is a strong base but $HF$ is a weak acid. The salt formed will be basic.
- For $2NH_4OH + H_2SO_4$: $NH_4OH$ is a weak base and $H_2SO_4$ is a strong acid. The salt formed will be acidic.
Answer:
$2NaOH + H_2SO_4$
