The measured pH of a prepared salicylic acid solution was 1.88. Based on this information, answer the items below. (Ka = 1.06 x 10-3) Determine the initial concentration (mol / L) of the acid in solution [Answer;Ci=0.177 mol/L] . And Knowing that salicylic acid is a solid, determine what mass the analyst must have weighed of the reagent to prepare 0.5 liters of this solution. (molecular mass of salicylic acid 138.12 g mol/L) [Answer; m=12.22 g]
