Each type of problem will require a different strategy.Write down the balanced chemical equation for the reaction between the acid and the base (this will typically be given to you in the problem as well).This trivia quiz is based on the titration problem of acids and bases that we learned and had some practice in the lab this week.

Then convert from p OH to p H by subtracting from 14.
Find the p H at equivalence if the problem asks you to do so.
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.
An acid is a substance that gives away protons, while a base is a substance that takes up protons.
Determine the ratio of the reactants using the chemical equation, i.e.
Solving Titration Problems
how many molecules of one chemical are needed to react with one molecule of the other.Titrations are hardly ever performed with a combination of a weak acid and a weak base, because it would be more difficult to find the equivalence point for this kind of titration.Write down what you know and figure out what the problem is asking for.By adding a chemical that reacts with the solute until all of the solute has been neutralized, the chemist can determine how much was originally present -- and hence the concentration of the solution.Titration problems with acids and bases are common assignments on homework and tests in chemistry class.Use the data you've been given to calculate p H at each step of the reaction if the problem asks you to do so (if not, skip this step and proceed to Step 6).Depending on the identities of analyte and titrant, there are four possibilities.For a strong acid paired with a strong base, the p H at equivalence is 7.For a strong acid titrant and weak base analyte, take the number of moles of weak base originally present and divide by the new total volume (original volume of analyte volume of titrant added to reach equivalence) to find concentration, then take the negative log of this concentration.Usually a homework or test problem of this kind will give you the identities of the titrant and analyte, the volume of analyte and the concentration of the titrant.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 p H 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 p H at each stage of the reaction.
