The formula below will also use the term V1. This is the volume of the acid we will be adding to water. We probably won’t use the entire bottle of acid, though, so we don’t know what this number is yet.

If you are using unusual units, convert them all to units of molar concentration (moles per liter) and liters before you continue. If you are not certain what concentration or volume of acid is required, consult your teacher, a chemist, or an expert in the task you plan to use acid in.

In our example, we can write this formula (6M)(V1)=(2M)(0. 5L).
In our example, we can write this formula (6M)(V1)=(2M)(0. 5L).
In our example, we would end up with V1=((2M)(0. 5L))/(6M)=1⁄6 liter (0. 0 US gal). This approximately equals 0. 167 liters (0. 0 US gal), or 167 milliliters.

In our case, we want to end up 0. 5 liters (0. 1 US gal) and will be using 0. 167 liters (0. 0 US gal) of acid. The amount of water we need = 0. 5L - 0. 167L = 0. 333L, or 333 milliliters. Always double-check your calculations to make sure that they’re accurate. [2] X Expert Source Chris Hasegawa, PhDRetired Science Professor & Dean Expert Interview. 29 July 2021.
Sometimes several cards are issued, depending on the concentration and additions to the acid. Pick the one that most closely matches your initial acid solution.
Tie up long hair before handling the acid. Acid can take several hours to burn holes through clothing. Even if you do not notice a spill, a few drops can damage your clothing if it is not underneath a lab coat.
When washing your eyes, keep your eyelids wide open. Rotate your eyes by looking up, right, down, and left to make sure all sides of your eyeball are rinsed.
Ventilate the area by opening windows and doors, and turning on fume hoods and fans. Apply a weak base such as sodium carbonate (soda ash), sodium bicarbonate, or calcium carbonate to the outer edges of the spill, avoiding the resulting spatter. Continue to apply slowly, working inward, until the spill is covered. Mix well with a plastic tool. Check the pH of the spill with litmus paper. Add more base if necessary to get the pH between 6 and 8, then flush the spill down a drain with plenty of water.
For most dilutions, the water can be at room temperature.
You don’t need to carefully measure this water, as long as it came from a container that was carefully measured to contain the total required amount of water.
Never use a mouth pipette in a chemistry lab.
This amount was calculated as V1 above.
