32. During pH-metric titration of a mixture of small amounts of NaOH and Na2CO3 with a 0.01 N HCl solution, the following results were obtained:
Volume of 0.01 N HCl, ml 1.00 3.00 10.60 11.00
pH of solution 11.25 11.12 4.00 3.80
Calculate the content of NaOH and Na2CO3 in the mixture if it is known that the volume of the titrated solution was 50 ml, and the content of Na2CO3 in it does not exceed 5*10-5 g-eq/l.
