After calculating the correct amount of water needed to dilute the acid to the desired pH level, use a flask of cooled, distilled water and add the acid to the water in small doses. Be very cautious when handling acids, as they can be harmful if they come into contact with the skin or if their fumes are inhaled.
When diluting acid with water, it is very important to always add the acid to the water and not the other way around. Also, it is important to wear a lab coat, goggles and gloves, and perform the dilution in a fume hood if possible so that the fumes will not be inhaled.
- Calculate the necessary amount of water
- Set up the materials for dilution
- Dilute the acid
Use the dilution calculating formula (the initial concentration multiplied by its volume equals the resulting concentration multiplied by its volume), to determine the amount of water needed to dilute the acid to its desired pH level.
Cool distilled water in the fridge or freezer and set up the proper safety equipment. Place the right amount of cool, distilled water in a flask that will be big enough to hold all of the water and acid.
Use a pipette to add small amounts of acid to the cooled water. The reaction will create heat, which is why it is important to add the acid to the cooled water and not the other way around.
