What is the pH of a neutral solution at 25°C?
Recall the definition of neutrality in terms of pH.
If a solution has a [H+] of 1.0 x 10^-5 M, what is its pH?
Use the formula pH = -log10 [H+].
What is the pH of a neutral solution at 25°C?
Think about what neutrality means in a pH context.
If [H+] = 1.0 x 10^-6 M, what is the pH?
Use the pH formula.
Given a 0.15M solution of hydrochloric acid, calculate its pH. Then, if the concentration of the acid is halved, what is the new pH?
Remember, strong acids fully dissociate.
Calculate the pH of a 0.01M solution of a weak acid with a Ka of 1.0 x 10^-5.
Make sure to use the ICE table for weak acids.
