Question

Why is CH3OH an Arrhenius base?

Answer 1

Its not!

Explanation:

An Arrhenius base is a substance that increases the concentration of hydroxide `("OH"^-)` ions once it dissolves in an aqueous solution. Methanol has `"-OH"` group, but it does not give `"OH"^-` ions in the aqueous solution.

The reaction would look like this:

`"CH"_3"OH" + "H"_2"O" -> "CH"_3"O"^(-) + "H"_3"O"^+`

Hope that helps! :)
