4 cards from this section. Quick, good the night before a test.
What is the pH of a solution with [H⁺] = 1.0 × 10⁻⁵ M?
Use the formula pH = -log₁₀[H⁺].
If a solution has a pH of 8, what is the pOH?
Use the relationship pH + pOH = 14.
What does a pH of 7 indicate?
Think about the middle point of the pH scale.
True or False: pH and pOH always sum to 14 at any temperature.
Consider how temperature affects the concentration of ions in water.
A 0.1 M solution of acetic acid has a Ka of 1.8 × 10⁻⁵. Calculate its pH.
Use the assumption for weak acids that x will be small compared to C₀.
If a solution has a pH of 4, what is the concentration of H⁺ ions in moles per liter?
Remember the inverse relation between pH and concentrations.
