Why is it crucial to add chemicals to water instead of the other way around?

Adding chemicals to water rather than the other way around is crucial for several reasons, particularly to prevent splattering and unwanted reactions. When a chemical is added to water, it is more likely to disperse evenly and react gradually. This method reduces the risk of heat or gas generation that can occur if water is introduced directly into a concentrated chemical. Certain chemicals can react violently when mixed with water, leading to hazardous situations, such as explosions or the release of harmful gases.

This controlled approach not only enhances safety but also ensures that the chemical mixture behaves predictably. Efficient mixing is certainly important, but it does not overshadow the primary concern of safety when handling potentially reactive substances. Similarly, chemical absorption and potency relate to the effectiveness of the chemicals but are secondary to the immediate safety risks associated with improper mixing.
