Answer:
[OH⁻] = 10⁻¹⁴/[H⁺].
Explanation:
∵ [H⁺][OH⁻] = 10⁻¹⁴.
∴ [OH⁻] = 10⁻¹⁴/[H⁺].
Answer:
[tex]Kw = [H+][OH-][/tex]
Explanation:
For a given solution H+ refers to the hydrogen ion concentration and is indicative of the acidity of the solution. The more the [H+] concentration, higher is the acidity. Similarly, OH- refers to the hydroxide ion concentration and reflects the basicity of the solution. A solution with a higher OH- concentration is said to be basic.
The two are related by considering the dissociation of water:
[tex]H2O(l)\rightleftharpoons H+(aq)+ OH-(aq)[/tex]
The dissociation constant for water, Kw is:
[tex]Kw = [H+][OH-]\\\\where\ Kw = 10^{-14} \\\\10^{-14} = [H+][OH-]\\[/tex]
[tex][H+] = \frac{10^{-14}}{[OH-]}[/tex]
