1. choose two of the acids listed, one monoprotic, the other diprotic. write the reactions that occur when each of them react with a solution of naoh. 2. to standardize a solution of naoh, one uses a primary standard called potassium hydrogen phthalate (khp for short). it is a monoprotic acid that can be obtained extremely pure and dried to a constant weight. it has a molar mass of 204.33 g/mol. suppose you weigh out 0.556 g of khp and dissolve it in water. it requires 14.48 ml of naoh solution to reach the endpoint. what is the concentration of the naoh solution? 3. the naoh solution from #2 above is used to titrate a diprotic acid solution of unknown concentration. 25.00 ml of the acid solution requires 26.54 ml of naoh solution. what is the concentration of the acid solution?

Abeaker contains a 25 ml solution of an unknown monoprotic acid that reacts in a 1: 1 stoichiometric ratio with naoh. titrate the solution with naoh to determine the concentration of the acid. perform a titration by setting the concentration of the naoh solution and adding it to the acid solution using the different add base buttons. the equivalence point of the titration is passed when the solution color changes. the unknown sample can be titrated multiple times by pressing the retitrate button and starting over. enter the concentration of the unknown acid solution.

Tartaric acid, h2c4h4o6, has two acidic hydrogens. the acid is often present in wines and precipitates from solution as the wine ages. a solution containing an unknown concentration of the acid is titrated with naoh. it requires 21.65 ml of 0.3000 m naoh solution to titrate both acidic protons in 50.00 ml of the tartaric acid solution. part a write a balanced net ionic equation for the neutralization reaction.
