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

Question:

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

Answer:

Concentration of H+ (hydrogen) ions

  • To know the nature of the solution, i.e., basic or acidic, the concentration of ions is needed.
  • To identify the solution, a pH value or the concentration of H+ ions is used.
  • The concentration of H+ ions increases as the solution turns acidic, whereas the concentration of H+ ions decreases when the solution is basic/alkaline.

pH Scale

  • It determines the measure of the hydrogen ion H+ concentration.
  • The solution is acidic if the value is less than 7, neutral when it's 7, and if it's greater than 7, the solution is basic in nature.
