What is the correct way to mix a strong acid and water?

Correct Answer: The acid must be slowly added to the water with constant stirring.

Subject: chemistry

• The water must be added rapidly to the acid.
• The acid and water should be heated before mixing.
• The acid must be slowly added to the water with constant stirring.
• The water must be slowly added to the acid.

Explanation: • <b>Key Fact</b> Dissolving an acid or a base in water is a highly exothermic process (releases huge heat). • <b>Supporting Detail</b> Acid must ALWAYS be added slowly to water with constant stirring. • <b>Related Concept</b> Adding water to concentrated acid can cause the mixture to splash out and cause severe burns. • <b>Why wrong options are wrong</b> Heating before mixing is dangerous as it increases the risk of boiling over. • <b>Exam Trick</b> AAA rule: Always Add Acid (to water). • <b>Additional Info</b> This process of mixing is called dilution, which decreases H₃O⁺/OH⁻ concentration per unit volume.
