When diluting a strong acid, what should be added to the other?

Water to Acid
Acid to Water
Base to Acid
Acid to Base

The correct answer is: Acid to Water

When diluting a strong acid, it is important to add acid to water rather than water to acid. This method is critical because adding water to a concentrated acid can cause an exothermic reaction, leading to the acid splattering and potentially causing burns or other injuries. By adding acid to water, the heat generated during the dilution process is absorbed by the larger volume of water, significantly reducing the risk of splattering. The water's ability to absorb heat allows for a more controlled and safe dilution process. This approach is standard practice in laboratories and educational settings for handling strong acids. Proper safety precautions should be taken regardless of the method, but the principle of adding acid to water is key to ensuring safety during the dilution process.
