A solution is prepared by dissolving 5.32 grams of potassium nitrite (a food preservative, as Clark Griswold would explain) into about100 ml of DI water in a volumetric flask. Enough water is then added to give a total volume of 250.0 ml. What are the equilibrium concentrations and the pH of the resulting solution?
What is the ph of a solution prepared by dissolving 0.140 g of potassium hydroxide in sufficient pure water to prepare 250.0 ml of solution?
what is the OH- of a solution prepared by dissolving .0912g of hydrogen chloride in sufficient pure water to prepare 250.0 ml of solution
