Question

What effect does the concentration of h+ ( aq) ions have on the nature of the solution?

Answer 1

When the concentration of hydrogen ions increase the solution become more acidic while when the hydrogen ion decreases cause an increase in the bases in the solution.

Answer 2

|$\large\bf\purple{Answer}$|

Hydrogen ion concentration decides the nature of the solution. If Hydrogen ion concentration increase then solution turn acidic and similarly if Hydrogen ion concentration decreases then solution turn basic.
