Why am I allowed to pour acids into water but I'm not allowed to pour water into acids?

This is a rule in our chemistry laboratory.

Two reasons:

1. Pouring water into acid can cause some of the acid to splash out of the container and possibly onto you. Doing the reverse is FAR less likely do cause this.

2. Some acids undergo an exothermic reaction when diluted. If this happens, a larger volume of water is needed to help distribute that generated heat as soon as possible.

Does that help?
