Q. which statement describes a general property of bases? a. they taste sour. b. they turn blue litmus red. c. they conduct an electric current in a solution. d. the concentration of h+ is greater than the concentration of oh-.

Answer : The correct options is, (C) They conduct an electric current in a solution.

Explanation :

Acid : It is a substance that has ability of donating proton or hydrogen ion, .

The properties of an acid are :

Base : It is a substance that has ability of donating hydroxide ion, .

The properties of an base are :

As we know that,  a base such as NaOH will dissociate in water to form sodium ion and hydroxide ion. So, the ions of an aqueous solution of base will conduct electricity.  That means the base conduct an electric current in a solution.

In acid, the concentration of hydrogen ion is greater than the hydroxide ion but in base the concentration of hydroxide ion is more than the hydrogen ion.

Hence, the correct options is, (C) They conduct an electric current in a solution.
