Question

When the procedure calls for making a more dilute solution of an acid, or mixing an acid with other solutions, what is the correct order of steps? Select one: a. Neither of these methods is safe. b. Always Add Acid - Either add all of the water or non-acid component first, or add a significant portion, before adding the acid to the mixture. This helps to minimize the heat generated, which could otherwise create dangerous fumes or reactions. c. Always Add Acid - the acid should be added first and then the other materials to prevent a dangerous reaction.

Answer 1

The correct order it b. always add acid last.

Step-by-step explanation:

Adding acid first could result on a violent reaction and heat or fumes can be generated. The best approach is to always add all the water or non-acid component first, or add a significant portion before adding the acid slowly to the mixture.
