Lab # 11 – Acid - Base Titration Introduction: The purpose of this lab is to determine the molarity (M) of an unknown HCl solution. A NaOH solution will be made and its molarity calculated. A sample of the NaOH solution will be titrated against the unknown HCl solution to calculated the volume needed to neutralize it. With these volumes the unknown molarity can be calculated. Theory: Solutions are made up of solvents and solutes. Materials known as acids when dissolved

Critical Thinking Questions 6.1 Identify the steps involved in computing the future value when you have multiple cash flows. First‚ prepare a time line to identify the size and timing of the cash flows. Second‚ calculate the present value of each individual cash flow using an appropriate discount rate. Finally‚ add up the present values of the individual cash flows to obtain the present value of a cash flow stream. This approach is especially useful in the real world where the cash flows for each

involves two oxidation-reduction reactions to calculate the oxidizing capacity of a sample of unknown bleach. In order to determine the volume of Na2S2O3 added‚ students will conduct a titration of bleach with thiosulfate with addition of a starch indicator to find the end point of the titration. Moreover‚ the oxidizing capacity of bleach is calculated with the percentage by mass of NaOCl in the unknown bleach sample. The overall chemical reaction throughout the experiment will be balanced with the
