Which of these properties would be possessed by both acids and bases? note: we do not mean mixing both in the same solution. we mean comparing a solution of an acid and a solution of a base. 1. they would taste bitter, if you were unwise enough to taste them. 2. they would react with metals and produce hydrogen gas. 3. they conduct electricity. 4. they turn litmus green. 5. they have a ph greater than 7. site: .com?

An Arrhenius base is a substance that dissociates in water to form hydroxide ions (OH⁻). 
In this example lithium hydroxide is an Arrhenius base:

LiOH(aq) → Li⁺(aq) + OH⁻(aq).

An Arrhenius acid is a substance that dissociates in water to form hydrogen ions or protons (H⁺). 
For example hydrochloric acid: HCl(aq) → H⁺(aq) + Cl⁻(aq).

4) red litmus turn blue whe base is drop on it and blue litmus turn red when acid is drop on it.

5) bases have pH greater than 7, acids have pH less than 7.

The properties that would possess by both acids and bases is they conduct electricity.

Acids are sour in taste and turn blue litmus paper to red.

They react with metals to liberate hydrogen.

Bases are solution that accept electron pair bonds.

NaOH is a base and HCl is an acid.

Thus, the correct option is 3, they conduct electricity.
