Answer:
The answer to your question is [H⁺] = 6.31 x 10⁻¹⁰ M [OH⁻] = 1.58 x 10⁻⁵ M
Explanation:
Data
[H⁺] = ?
[OH⁻] = ?
pH = 9.2
Process
To find the answer to this question we must start by using the formula of pH and simplify to find the [H⁺] then calculate the pOH to find the [OH⁻]
1.- Write the formula of pH
pH = -log [H⁺]
2.- Find the [H⁺]
9.2 = -log[H⁺]
-Solve for [H⁺]
[H⁺] = antilog (-9.2)
-Result
[H⁺] = 6.31 x 10⁻¹⁰ M
3.- Calculate the pOH
pH + pOH = 14
-Solve for pOH
pOH = 14 - 9.2
-Result
pOH = 4.8
4.- Calculate the [OH⁻]
-Substitution
4.8 = -log [OH⁻]
-Solve for [OH⁻]
[OH⁻] = antilog (-4.8)
-result
[OH⁻] = 1.58 x 10⁻⁵ M
