experiment you performed. Try to predict what would happen if you did the acid - base titration with different concentrations of NaOH in the coffee cup. What would be the pH change in each case? What would be the extent of change in the temperature? What will be the effect of reacting other acids (such as, for example, acetic acid) with NaOH?

Use different concentrations of NaOH with a constant concentration of HCl. Calculate unknown concentrations of the titrated NaOH (or HCl). This can be done by setting the flow of acid (or base) from the burette pipette at a constant rate. Use this flow rate together with the time data from your graph to calculate the amount of titrant added to the solution. Perform acid-base titrations with different types of acids and/or bases: A weak acid with a strong base and vice versa.
