Sulfuric Acid with a molarity of .001 has a pH of 2.75. You want to dilute 1mL of this acid to a pH of 5.2. If you want to dilute 1mL of the original solution, what would the final volume of solution be?
For the original solution:
For the target solution:
This means the dilution factor to go from pH 2.75 to pH 5.2 will be:
This means you take 1 ml of the original solution and make it up to a final volume of 282.1 ml
