How will the concentration of h+ and oh− ions change when a substance with a ph 11.4 is added to water? both h+ and oh− will increase both h+ and oh− will decrease h+ will increase and oh− will decrease h+ will decrease and oh− will increase

Answer : The correct option is, will decrease and will increase

Explanation :

As we know that the water is made up of the and ions. When a substance with a pH 11.4 that means the solution is basic in nature is added to water, the concentration of ions increase and the concentration of ions decreases.

In the basic solution, the concentration of ions are more than the concentration of ions. So, when a base is added to the water the more ions dissociates in the water as compared to the ions.

Hence, the correct option is, will decrease and will increase

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).
