To convert pOH to pH, subtract it from 14. According to my professor's handout the pH is determined by the excess of hydroxide--is this wrong? Sciencing Video Vault. Determine whether the analyte the chemical dissolved in the solution and the titrant the chemical added to neutralize the solute are strong acids or bases.

Post as a guest Name. No matter which method is used, some error is introduced, so the concentration value is close to the true value, but not exact.

Sourav Suman Sourav Suman 11 1 5. The problem might give you the amount of titrant needed to reach equivalence the point where all the solute has been neutralized and ask you to find the pH at equivalence and the concentration of the original solution, or it might give you the concentration of both titrant and solute then ask you to find the pH at each stage of the reaction.

Strong Acid Strong Base Titration Problems with pH Calculations

Use the data you've been given to calculate pH at each step of the reaction if the problem asks you to do so if not, skip this step and proceed to Step 6. Divide the number of moles of analyte by original volume of analyte to find the analyte concentration.

Each type of problem will require a different strategy. How to solve titration problem?

Titration problems with acids and bases are common assignments on homework and tests in chemistry class. Tip This procedure assumes a 1-to-1 ratio between acid and base in the neutralization reaction -- which is typically the kind of problem you'll see on a general chemistry quiz. There are different methods used to determine the equivalence point of a titration.

Find the pH at equivalence if the problem asks you to do so. Home Questions Tags Users Unanswered. Sign up using Facebook. Find the original concentration of the analyte if the problem asks you to do so. Usually, the error here is to go past the equivalence point, giving a concentration value that is too high.

The above steps can be reduced to one equation. The endpoint is a sort of "best guess" based on the experimental data. Copyright 2019 Leaf Group Ltd. By using our site, you acknowledge that you have read and understand our Cookie Policy , Privacy Policy , and our Terms of Service.

Then convert from pOH to pH by subtracting from 14.
