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. 1. What is the pH of this buffer?
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.
1. What is the pH of this buffer?
2. Write the equation by which this buffer would react to a strong acid.
3. If 50.0 mL of 0.0750M nitric acid is added to the original buffer, what would be the pH?
4. Write the equation by which this buffer would react to the addition of a strong base.
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?
6. You add 450 mL of a 0.27M hydrochloric acid solution to the original buffer. What is the pH of the resulting solution?
