[OH] vs [H]

[andrea tarelo 3e]

What is the difference between when you get the [OH] vs [H] value? I know that they differ somehow but I am confused as to how.

[905749989]

Well they are different in that [OH] represents the concentration of hydroxide in a solution and [H] represents the concentration of hydronium in a solution. In terms of solving for pH and pOH, they vary in that the [OH] correlates with the pOH value and the [H] correlates with the pH.

[JacksonWissing2G]

Your [H] value will pretty much be responsible for the pH of the solution, as pH = -log[H]. [OH] however is inversely proportional to [H], as it shows the amount of OH in the solution instead of H. In this case pOH = -log[OH], but it’s also equal to 14 - pH. Having an [H] value that corresponds to a lower pH would mean the solution would be more acidic, while higher pH would mean it would be more basic. [OH] is the opposite, with lower pOH values meaning more basic and higher values being more acidic.

[OH] refers to the concentration of hydroxide while [H] refers to the concentration of hydronium. The concentration of [H] and [OH] in a solution multiplied should equal 10^-14.

[Aanya Pramanik 1C]

[OH-] is the concentration of hydroxide and is associated with bases. You use [OH-] to calculate pOH by doing -log[OH-]. [H+], on the other hand, is associated with acids and is the same as the [H3O+] hydronium concentration. You use this to calculate pH by doing -log[H+].

[Violet Mbela 2B]

[OH] is hydroxide and [H] is hydronium. Hope that helps!

[Cecilia Lei 3K]

The concentration of OH- times the concentration of H+ will be 10^-14, and that’s the reason why pOH+pH=14.

Hi,

I think you are definitely right that they exists a special correlation.

[OH] represents the concentration of Hydroxide in the solution, while [H] represents the concentration of [H3O+] in the solution, and you could use pH value to calculate with them each respectively to help get the value of pH and pOH of the solution.

Note that pH and pOH are complementary because they respectively represent the acidity and alkalinity of the solution. So that it's not difficult to say that pH+pOH= a constant. We regulate that the constant is 14.

Therefore, pH+pOH=14.

Hope this could address your concerns.

[Anisa Morales 1L]

The difference is that [OH] is the concentration of Hydroxide in the solution while [H] is the concentration of hydronium (H3O+) in a solution.

[Kiana Rogers 1E]

[OH] is Hydroxide and [H] is Hydronium. This can be used to find the pH (pH = -log[H+]) and pOH (pOH = -log[OH-].

[Michael 1G]

[OH-] would be the concentration of hydroxide ions in solution while [H+] is the concentration of hyrdronium ion. If you take the inverse log of each value you will be able to find the pOH and pH of a solution.

[Clayton Dinh 3C]

H = hydronium while OH = hydroxide. They both can be used to find the pH or pOH of the solution.
