In titration, one solution is added to another solution until a chemical reaction between the components in the solutions has run to completion. The solution being added is called the titrant, and we say that it is used to titrate the other solution. The completion of the reaction is usually shown by a change of color caused by a substance called an indicator. A typical titration proceeds in the following way. A specific volume of the solution to be titrated is poured into an Erlenmeyer flask. For example, 15.0 mL of a sulfuric acid solution of unknown concentration is added to a 250 mL Erlenmeyer flask. An indicator is then added to the flask, which changes color when the reaction is complete. The titrant in this example is potassium hydroxide, having a concentration of 0.121 M. The titrant is added to a buret. After slowly adding the titrant to the flask, the reaction is complete when a color change occurs. If 11.4 mL of KOH was added to the flask, what is the molarity of the sulfuric acid solution? For this assignment, write and balance the molecular equation for KOH and H2SO4. Then show all work and final units for the molarity of the sulfuric acid solution.

You have a solution that is either CuCl2 (aq) or Cu(NO3)2 (aq). You add some KOH (aq) and a solid precipitate is formed. Does this test allow you to determine the contents of your solution?

79. A solution contains an unknown mass of dissolved barium ions. When sodium sulfate is added to the solution, a white precipitate forms. The precipitate is filtered and dried and found to have a mass of 258 mg. What mass of barium was in the original solution? (Assume that all of the barium was precipitated out of solution by the reaction.)
The compound barium hydroxide is a strong electrolyte. Write the reaction when solid barium hydroxide is put into water.
13. A chemistry student offers a possible improvement to this lab. Since one goal of this lab is to determine the mass of the precipitate produced, wouldn't it be possible to measure the mass of an empty beaker, mix the solutions, and boil off the water until it is entirely evaporated, leaving only solid behind? Then the beaker with the precipitate could be weighed, and the difference between this mass and that of the empty beaker would be the mass of the precipitate. This would eliminate the need for the filtration step. Explain why this is a poor suggestion. Remember to check your reasoning on this question and all other questions with your instructor.
