A buffer is prepared by adding 2.50g of lithium fluoride to 125 mL of 0.648M hydrofluoric acid. You may assume there is no change in volume after the substances are mixed. 5. You add 75.0 mL of 0.900M potassium hydroxide to this buffer. Assuming no change in volume, what would be the pH after this addition?
