Addition of phenolphthalein to an unknown colorless solution does not cause a color change. The addition of bromthymol blue to the same solution leads to a yellow color. Which of the following can you establish about the solution: (i) A minimum pH, (ii) A maximum pH, or (iii) A specific range of pH values?
Calculate the pH of a solution formed by adding 5.00 grams of solid sodium formate, NaCHO₂, to 180.0 ml of 0.220 M formic acid solution, HCHO₂. You may assume that the salt dissolves completely and that the change in volume is negligible upon addition of the solid.
A chemist wishes to prepare a standard aqueous solution that has a concentration of Fe3+ equal to 1.0x10-5 M. This solution is to be prepared by allowing water at a set pH to reach equilibrium with solid Fe(OH)3. Given the fact that pH = -log [H+], what pH should be used for the aqueous solution to give this desired concentration of [Fe3+].
