Answer:
Basic solution.
Explanation:
∵ pOH = -log[OH⁻] = - log(1.0 x 10⁻⁴) = 4.
∵ pH + pOH = 14.
∴ pH = 14 - pOH = 14 - 4 = 10.
Since, the pH of the solution is 10 (> 7) and the concentration of [OH⁻] is 1.0 x 10⁻⁴ (> 1.0 x 10⁻⁷) is a basic solution.
Answer:
The solution is basic
Explanation:
Given:
Concentration of OH- = 1*10⁻⁴ m
To determine:
The nature of the solution i.e. acidic or basic
Formula:
A solution where the pH = 7 is neutral
pH < 7 is acidic
pH > 7 is basic
[tex]p[OH] = -log[OH-] = -log[1*10^{-4}] = 4\\ \\p[H] + p[OH] = 14\\\\Therefore\ pH = 14 - p[OH] = 14 - 4 = 10[/tex]
Since, pH > 7, the solution is basic
