Acids are substances that have a rich concentration of the proton H+. Acids are bitter in taste and have a pH less than 7. Substances with pH greater than 7 are basic solutions while that at 7 are called neutral solution. The answer to this problem is A. Acids give foods a bitter taste. 

Answer : The correct options is, (B) Aqueous solutions of acids conduct electricity.

Explanation :

Acid : It is a substance that has ability of donating proton or hydrogen ion, [tex]H^+[/tex].

The properties of an acid are :

  • Acids are sour in taste.
  • The texture of an acid solution is sticky.
  • It changes the color of the litmus paper to red.
  • It react with a metal to give compound and hydrogen gas.
  • An aqueous solution of an acid conduct electricity.
  • The pH value of acid is less than 7.

Base : It is a substance that has ability of donating hydroxide ion, [tex]OH^-[/tex].

The properties of an base are :

  • Base are bitter in taste.
  • The texture of an base solution is slippery.
  • It changes the color of the litmus paper to blue.
  • It does not react with a metal.
  • An aqueous solution of an base also conduct electricity.
  • The pH value of base is greater than 7.

Hence, the correct options is, (B) Aqueous solutions of acids conduct electricity.
