How do you calculate the concentration of an acid from titration data?

You calculate the concentration of an acid from titration data using the formula: concentration = moles/volume.

In a titration, you're essentially reacting an acid with a base to determine the concentration of the unknown solution. The process involves a few steps. First, you need to know the volume of the acid used in the titration and the concentration of the base.

The first step in the calculation is to determine the number of moles of the base used. This is done by multiplying the volume of the base (in litres) by its concentration (in moles per litre).

Next, you need to use the balanced chemical equation for the reaction to find out how many moles of acid react with the base. This is known as the stoichiometry of the reaction. For example, in the reaction between hydrochloric acid and sodium hydroxide, one mole of acid reacts with one mole of base.

Once you know the number of moles of acid, you can then calculate the concentration of the acid. This is done by dividing the number of moles of acid by the volume of the acid (in litres).

Remember to always convert your volumes to litres (by dividing by 1000 if your volume is in millilitres) and your concentration will be in moles per litre, which is also known as molarity.

In summary, the concentration of an acid from titration data can be calculated using the formula: concentration = moles/volume. This involves knowing the volume and concentration of the base used, the stoichiometry of the reaction, and the volume of the acid.
