1. Calculate the mass of NaOH necessary to make a 1L of a 0.1 M solution 2. Make the solution by dissolving the mass of base, NaOH, needed with the distilled water in a beaker only enough to dissolve it. 3. Pour the solution in to an Erlenmeyer flask. Pour in distilled water till you have a 1 L solution. 4. Mass 0.25g, 0.35g, 0.45g, and 0.5g samples of KHP. 5. Dissolve each sample in 30ml-distilled water. Add two drops of bromothymol blue indicator. 6. Fill a burette with you NaOH base and record the initial reading. 7. Titrate the base into one of the acid samples to a blue color. 8. Record the amount of base needed and calculate the molarity of the base. 9. Repeat the titration with other samples. 10. Four results should be obtained and averaged. 11. You have found the base molarity
