Answer the following questions on the multiple choice answer sheet provided. Dilute the available NaOH solution with an equal volume of water. Weigh 50 mL of the available NaOH solution in order to calculate the density and proceed from there. Dilute 40 mL of the available solution to 50 mL with water. The appropriate volume of the available solution can be used as is.
Insufficient information is provided to answer the question.
There is not enough information given to calculate the molarity. A pH meter titration will reveal the pH region of the stoichiometric endpoint and thus can be used to select an appropriate acid-base indicator for the titration. A pH meter actually measures the voltage difference between the solution measured and a standard solution inside the electrode. A pH meter is best calibrated with two buffer solutions of known concentration. All of the above are true.
