Kw is a constant number under same temperature. So when [OH-] decrease from 10^-9 to 10^-1, the [H+] will increase. So the answer is a. increases.
Answer:
[H⁺] increases
Explanation:
Kw = [H⁺][OH⁻]
[OH⁻] = 10⁻⁹
Kw = 1 x 10⁻¹⁴
[H⁺] = Kw / [OH⁻] = 1 x 10⁻¹⁴ / 10⁻⁹= 10⁻⁵
[OH⁻] = 10⁻¹¹
Kw = 1 x 10⁻¹⁴
[H⁺] = Kw / [OH⁻] = 1 x 10⁻¹⁴ / 10⁻¹¹= 10⁻³
As the concentration of OH⁻decreases, the concentration of H⁺ increases.
