Question

if a base is added to water, what will occur,

a) hydronium ion concentration is increased.

b) hydroxide ion
concentration is decreased.

c) [H+] is decreased.

d) [OH+] is decreased.

Answer 1

H+ is decreased LMK if this helped

Answer 2

Answer : The correct option is, (c) $[H^+]$ is decreased.

Explanation :

As we know that water contains hydrogen ions and hydroxide ions.

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

Base : It is a substance that has ability of donating hydroxide ion, $OH^-$.

As per question, when a base is added to the water then water become basic due to increase in concentration of hydroxide ion. And the concentration of hydrogen ion decreases.

Hence, the correct option is, (c) $[H^+]$ is decreased.
