9. In standardizing roughly 0.05M H, SO, solution,1.325g of pure an hydrous sodium
carbonate were made up to 250cm' and 25cm' of the solution needed 23.5 cm of
the acid. Calculate the concentration of the acid in gom*. If 906cm? of the acid
were left after the titration, how many cm' of water must be added to the
remaining acid to make it exactly 0.05M?(Ans 5.212, 57.82) SOMEONE PLEASE EXPLAIN HOW TO DO IT!!
