Questions: What is the name for the H3O+ ion? What is the name of the OH- ion?
Transcript text: What is the name for the $\mathrm{H}_{3} \mathrm{O}^{+}$ ion? What is the name of the $\mathrm{OH}^{-}$ ion?
Solution
Solution Steps
Step 1: Identify the $\mathrm{H}_{3} \mathrm{O}^{+}$ ion
The $\mathrm{H}_{3} \mathrm{O}^{+}$ ion is known as the hydronium ion. It is formed when a proton ($\mathrm{H}^{+}$) associates with a water molecule ($\mathrm{H}_{2}\mathrm{O}$).
Step 2: Identify the $\mathrm{OH}^{-}$ ion
The $\mathrm{OH}^{-}$ ion is known as the hydroxide ion. It is a negatively charged ion consisting of one oxygen atom and one hydrogen atom.
