Consider 50 ml of a solution that is 0.25 m in both h2po4− and hpo42−. (a) what is the ph of this solution? (enter your answer to two decimal places.) (b) what would be the effect of adding 5 ml of 1.0 m hcl? the ph would decrease slightly. the ph would decrease dramatically. the ph would increase slightly. the ph would increase dramatically. the ph would not change at all. (c) what would be the effect of adding 2 ml of saturated naoh (50 mass %, density 1.5 g/ml)? the ph would decrease slightly. the ph would decrease dramatically. the ph would increase slightly. the ph would increase dramatically. the ph would not change at all.
