Compute the molarity of the ha and hb solutions

Reference no: EM13191787

On a lab exam, you have to find the concentrations of the monoprotic (one proton per molecule) acids HA and HB. You are given 40.6 mL of HA solution in one flask. A second flask contains 33.6 mL of HA, and you add enough HB solution to it to reach a final volume of 50.0 mL. You titrate the first HA solution with 87.4 mL of 0.0906 M NaOH and the mixture of HA and HB in the second flask with 94.0 mL of the NaOH solution. Calculate the molarity of the HA and HB solutions.
