A 100mM/L solution of Free-chlorine stock solution was used to make up 6 standard solutions (known concentration). See the table below with gives the test tube number, the amount of stock solution used and the amount of distilled water used to make up these solutions.

Use the M1V1 = M2V2 formula where M1 is the molarity of the stock solution, V1 is the volume of stock solution, and V2 is the final volume of the solutions (10.00 mL) to calculate the concentration of Free-chlorine in each of the 6 solutions. Record the calculated numbers into the table above. Ex: Test tube 0
M1= 100. mM V1 = 1.00 mL V2 = 10.00 mL
(100. mM) (1.00 mL) = M2 (10.00 mL)
M2 = 10.00 mM

Salicylic acid is a very important acid. it is used to synthesize the aspirin by treating with acetic anhydride. a 0.2015-g sample of salicylic acid was dissolved in a 100.00-ml volumetric flask, and the solution was diluted to the mark. a 10-ml aliquot of this solution was titrated with standard naoh (0.01130 + 0.2% n) to a phenolphthalein faint pink color end point at 19.81 ml. (a) (calculate the normality of the salicylic acid solution used in the titration. (b) assuming the salicylic acid is pure, what is the equivalent weight of the salicylic acid? practice problems for the final exam (continued) (c) (calculate the inherent error in the determination of the equivalent weight you calculated in part (b). use the following absolute errors in the equipment /glassware when calculating the inherent error. 5.00-ml pipet: + 0.02 ml 100-ml volumetric flask: + 0.08 ml analytical balance: + 0.2 mg 25-ml buret: + 0.03 ml
