Neutralizing or even diluting a concentrated acid can be very

exothermic. It can even cause the solution to boil if you are not

careful! This is extremely dangerous!

This is why when diluting concentrated acids (any kind) you

should ADD ACID TO WATER and not the opposite.

See the link below for more information about this important

safety issue in the laboratory due to the exothermic nature of this
