Which statement describes a general property of bases?

they taste sour.

they turn blue litmus red.

they conduct an electric current in a solution.

the concentration of h+ is greater than concentration of oh- .

The correct answer is "They conduct an electric current in a solution. "

Acids taste sour, and they turn blue litmus paper red. Also acids such as HCl when dissociates in water it releases H⁺ ions. Thus in an acid the concentration of H⁺ is greater than OH⁻.

HCl + H₂O -> H⁺ + Cl⁻

A base such as NaOH will dissociate in water to form Na⁺ and OH⁻. The ions of an aqueous solution of base will conduct electricity.

NaOH + H₂O -> Na⁺ + OH⁻

answer: c.

explanation:

i think it is true since you can test the answer and can use observations to complete it.
