If the [H+] in a solution is 1 × 10–1 mol/L, what is the [OH–]? Show your work.

AVprozaik [17]

Hello!

The basic equations to solve this is
pH = -log[H+]
pOH = -log[OH-]
pH + pOH = 14
------------------------------------------------------------------------------------------------------
Find pH

pH = -log(1 * 10^-1)
pH = 1
------------------------------------------------------------------------------------------------------
Find pOH
1 + pOH = 14

pOH = 13
------------------------------------------------------------------------------------------------------
Find OH-
[OH-] = 10^(-pOH)
[OH-] = 1 * 10^-13mo/L

The answer is $[OH-] = 1 * 10^{-13} mol/L$

Hope this helps!

When a reaction results in an almost complete conversion of reactants to products, chemists say that the reaction goes to comple

Agata [3.3K]

Yes, that is completion reaction.
This type of reactions do not set up an equilibrium and goes until one of the reactants runs out.
Three major types of completion reactions are:
1. Formation of a slightly ionized product (for example mixture of sodium bromide and potassium chloride).
2. Formation of a gas (for example hydrogen gas from metal and acid).
3. Formation of a precipitate (feor example silver chloride).
