प्रश्न
You have two solutions, A and B. The pH of solution A is 6 and pH of solution B is 8. Which solution has more hydrogen ion concentration? Which of this is acidic and which one is basic?
उत्तर १
A pH value of less than 7 indicates an acidic solution, while greater than 7 indicates a basic solution. Therefore, the solution with pH = 6 is acidic and has more hydrogen ion concentration than the solution of pH = 8 which is basic.
उत्तर २
pH of solutions, A = 6
∴ H+ ion concentration = 10-6 M.
pH of solution B = 8.
∴ H+ ion concentration = 10-8 M.
As 10-6>10-8, hence solution A has more H+ ion concentration.
A solution with pH < 7 is acidic. Hence, solution A is acidic.
A solution with pH > 7 is basic. Hence, solution B is basic.
