How do you interpret titration data to find concentration?

You interpret titration data to find concentration by using the formula: concentration = moles/volume.

In a titration experiment, you're essentially reacting two solutions together to find out how much of one solution is needed to neutralise the other. This allows you to calculate the concentration of the unknown solution. The key data you need from the titration are the volume of the solution of known concentration (the titrant) that was required to neutralise the unknown solution, and the concentration of the titrant.

The first step in interpreting titration data is to calculate the number of moles of the titrant used. This is done by multiplying the volume of the titrant (in litres) by its concentration (in moles per litre).

Next, you need to consider the balanced chemical equation for the reaction. This will tell you the ratio in which the two substances react. For example, if the equation shows that one mole of the titrant reacts with one mole of the substance in the unknown solution, then the number of moles of the unknown substance is the same as the number of moles of the titrant. If the ratio is different, you'll need to adjust your calculation accordingly.

Finally, you can calculate the concentration of the unknown solution by dividing the number of moles of the substance it contains by its volume (in litres). This gives you the concentration in moles per litre, which is usually reported in units of molarity (M).

Remember, it's important to ensure that all volumes are in litres and all concentrations are in moles per litre when doing these calculations. This will ensure that your final answer is in the correct units.
