Answer 1

By adding acid to water with constant stirring.

Explanation:

Diluting acid is highly exothermic, meaning it releases a large amount of heat. When you add acid to water, the larger volume of water helps absorb and dissipate heat safely. Adding water to acid instead can cause the mixture to flash-boil and splash corrosive liquid out of the container.
