Need help classifying these things. Please and thank you!

Question

classify each property as belonging to acid, base, or both

Hydroxide ions

           neutral         acid         both         base      

Hydronium ions

        neutral         acid         both         base      

Turns blue litmus red

           neutral         acid         both         base      

Slippery texture

              neutral         acid         both         base      

Answer 1

So Hydroxide (OH^-) is a base. This is actually the concentration that you use to find out how basic an aqueous solution is (pOH= -log[OH^-]).

Hydronium ions are acidic, and are used to calculate the pH (pH= -log[H₃O⁺]).

Acids turn litmus paper red, and bases turn litmus paper blue, therefore this is an acid.

Slippery texture - Think of your soap. Soap is very basic! It feels slippery because it reacts with your oils in your skin - saponification.
