Question

Sodium hydroxide + Hydrochloric acid $\to$

• A. Sodium chloride + Water
• B. Sodium chloride + Water + Heat
• C. Water + Heat
• D. Sodium + Heat

Answer 1

Answer: (B)

Sodium chloride + Water + Heat

When acids react with base they give salt and water and this reaction is known as neutralization reaction.

When strong acids such as $HCl$ (hydrochloric acid) reacts with strong base like $NaOH$ (sodium hydroxide), then neutral salt such as $NaCl$ (sodium chloride) and water are formed.

$NaOH+HCl\to NaCl+H_{2}O$

Hence, the correct answer is option (B).
