3 cards from this section. Quick, good the night before a test.
What is the pH of a neutral solution at 25 °C?
Remember what defines neutrality in pH terms.
If [H⁺] = 1.0 x 10⁻⁴ M, what is the pH?
Use the formula pH = -log₁₀[H⁺].
What is the relationship between pH and pOH?
Think about the definitions of pH and pOH.
At 25 °C, K_w is equal to?
Recall the value of K_w at standard temperature.
If a solution has a pH of 8, what is the [H⁺] and [OH⁻] concentration? Show your calculations.
First, calculate [H⁺] using the pH value, then use K_w to find [OH⁻].
A researcher has a solution where [OH⁻] is measured at 1.0 x 10⁻¹² M. Determine the pOH and pH.
Start by calculating pOH then use the earlier relationship to find pH.
