A series of solutions containing NAOH, Na,CO, and NaHCO, alone or in compatible combination, was titrated with o.1202 M HCI. Tabulated below are the volumes of acid needed to titrate 25.00-mL portions of each solution to (1) a phenolphthalein and (2) a bromocresol green end point. Use this information to deduce the composition of the solutions. In addition, calculate the mass in milligrams of each solute per milliliter of solution.
