an aqueous strong acid solution is diluted by adding more pure water. what happene to the pH of this solution? a) pH re...
Adding a few drops of a strong acid to water will change the pH of the water significantly. However, adding the same amount of strong acid to a buffer solution doesn't alter the pH significantly. Explain what happens to the pH of the water when the acid is added and why the pH for the water and the buffer solution will be significantly different. DSC-Paragraph BLU-
If 20.0 mL of glacial acetic acid (pure HC2H3O2) is diluted to 1.30 L with water, what is the pH of the resulting solution? The density of glacial acetic acid is 1.05 g/mL. Express your answer to two decimal places. pH =
