When  a base  is added  to water, hydronium   ions   decrease


Explanation


  •  Base  dissociate to give  out  OH-  ions
  •  In the other hand ,when  water (H2O)   dissociate it  give out hydronium ions ( H3O+)    and OH- ions
  • when  base  is added to  water  more OH-   it  led  to  addition of more Oh- ions  hence  H3O+ decrease.

 

When we add a base to the water, then the concentration of H⁺ ions is decrease.

What is base?

According to the Arrhenius theory of acids and base, bases are those substances which gives hydroxide ions (OH⁻) to the solutions.

As we know that water (H₂O) molecules dissociates into hydronium ions (H⁺) ion and hydroxide ions (OH⁻). So when we add base in the water then this base gives hydroxide ion to the solution as a result of which concentration of OH⁻ ions increases in the solution and concentration of H⁺ ions decreases.

Hence, option (2) is correct i.e. decrease.
