Question

While mixing sulphuric acid and water which of the following precaution should be taken?

• A. Add whichever is lighter to the heavier one
• B. Add acid to the water
• C. Add water to the acid
• D. Avoid sunlight

Answer 1

The correct option is B Add acid to the water

Acid should be added to water. If water added to acid then the first drop added to acid reacts explosively and might produce heat i.e. enough to boil the water instantly which spray the acid out of the container and can harm us.
