What is the concentration of a strontium hydroxide solution if its pH is 12.20? Answer is...
A chemist must prepare 850.0 mL of potassium hydroxide solution with a pH of 12.20 at 25°C. He will do this in three steps: . Fill a 850.0 ml volumetric flask about halfway with distilled water. • Weigh out a small amount of solid potassium hydroxide and add it to the flask. • Fill the flask to the mark with distilled water. Calculate the mass of potassium Hydroxide that the chemist must weigh out in the second step. Round your...
