Adding acid to water is the correct method for handling acids safely. This approach helps to minimize the risk of exothermic reactions that can occur when water is added to concentrated acid. When water is poured into concentrated acid, it can cause the acid to heat rapidly and potentially splatter, leading to dangerous situations. By adding the acid slowly to the water, the water can absorb the heat generated in a controlled manner, reducing the likelihood of splashing and ensuring a safer mixing process.

Utilizing safety gear is also a crucial practice when working with acids; however, it does not describe the proper handling procedure for mixing the substances. Therefore, while safety gear is important, it is secondary to the specific method of combining water and acid.
