A 0.1276g sample of a monoprotic acid (molar mass = 1.10 x 10^2) was dissolved in 25.0 ml of water and titrated with 0.0633 M NaOH. After 10.0 ml of base had been added
Divers experience a problem known as the bends when they come up to the surface too fast. Write an essay linking this phenomenon with solubility.
Then 40.0 mL of this solution were titrated with 0.060 M HClO4. Calculate the pH at the first equivalence point.
thomas poured 25 mL of 0.50 M HCl into a large bottle. He then added enough water so that the new (diluted) concentration was 0.10 M HCl. How much water did Thomas add?
One beaker contains 10.0 mL of acetic acid/sodium acetate buffer at maximum buffer capacity and another contains 10.0 mL of pure water. Calculate the hydronium ion concentration and the pH after the addition of 0.25 mL of .10 M HCl to each one.
