The analyte you are evaluating has a purity of 90.00% (by mass). You prepare a solution of the analyte NaHCO3 (MW= 84.01 g/mol) in water by taking 1.800 g of it and diluting it to a final volume of 100 mL. In the titration of this analyte solution with 0.100 M KOH answer the following question

Assume for H2CO3 that Ka1= 2.3 x 10^-5, and Ka2=1.6 x 10^-8

What is the initial pH of the analyte solution before the titration begins?
