Q&A for How to Perform a Titration

In a back titration, you know the concentration of an excess reactant, but you still need to find out the concentration of your analyte. It’s useful in situations where the direct titration endpoint is difficult to identify, such as when you’re doing weak acid and base titrations.

The equivalence point is the point at which the number of moles of titrant and analyte are equal. The endpoint is the change in the solution that you measure at the end of the titration.

The 4 types are acid base titration, redox titration, precipitation titration, and complexometric titration.

The tapered sides and narrow neck of the conical Erlenmeyer flask allow the contents inside to be mixed by swirling, without risk of spillage.

This depends simply on your analyte and what you are searching for in it. If you want to simply calculate the acidity of your analyte with the titration method, then you are expected to use a neutralizing alcaline solution for the process. The mechanism of titration is neutralizing the nature of your analyte so that the indicator you used changes color, that way, you can calculate how much neutralizing solution (and active substance) you have got to use, this way you can calculate the actual volume of let's say acidity level, referring to above example, there is in your sample (analyte). Your titrant solution has to be serving to your goal for using the titration.

I would just rapidly turn the stopcock and let some of the titrant flow out.

Water dilutes the solution, and the concentration will not be accurate.

Calculate the volume of titrant solution you used by tracking it over the burette. Record the exact volume of titrant solution you used. Know what is the density of your titrant. Usually (if not prepared by yourself) the package contains the volume density of active substance in the solution. If you prepared your titrant by yourself, you already know the volume density, molarity or normality of the solution you have prepared. Now that you have all the information you need, simply calculate how much active ingredient there was in the volume of the titrant solution you used, to neutralize your analyte.

Mass over molar mass times number of moles. You can also use number of moles over volume.

A titration calculation is a simple formula used to work out the concentration (in moles) of one of the reactants in a titration using the concentration of the other reactant. The article above sets forth all the steps you need to use to perform one effectively.

You could get more accurate measuring equipment; for example, instead of a mark every 5ml, use one that has a mark every ml or twice each ml.

Putting a white tile under the beaker with analyte increases contrast and makes it easier to see the change in colour.

The pipette is used to measure the quantity of the analyte; the chemical substrate whose concentration is to be determined.
