Scoring Scheme: 3-3-2-1.
Calculate and enter the molarity of your three HCl standardization trials using the volume of standardized NaOH solution required for each and the average molarity of the NaOH solution from the standardization trials with KHP. You should report 3 significant figures, e.g. 0.488 M.
Since you have used 0.1 M NaOH and titrated with 5 mL of HCl the molarity of the HCl can be... View the full answer

- alternatively, Since you have used 0.1 M NaOH and titrated with 5 mL of HCl the molarity of the HCl can be calculated using the formula N1V1=N2V2 NHCl x VHCl = NNaOH x VNaOH Trial 1: 5 x NHCl = 9 x 0.1M NaOH NHCl = 0.180 M HCl Trial 2: 5 x NHCl = 9.8 x 0.1M NaOH NHCl = 0.196 M HCl Trial 3 : 5 x NHCl = 9.7 x 0.1M NaOH NHCl = 0.194 M HCl
