When the ratio is given in parts, there is no strict rule on the units of measurement. It is a general term that is applicable to any unit. For example, the unit here is in mL. Since the ratio is 2 parts acid to 1 part water, that is also equivalent to 2 mL acid to 1 mL water. Hence, you have to add 2 mL of acid to water, not vice versa. Other acids are highly reactive to water. So, you have to add the acid slowly to avoid violent reactions.
