Question

15. You are given two solution A and B. The P H of the solution A is 6 and P H of solution B is 8. i) which solution is acidic and which solution is basic? ii) Which solution has more H + ion concentration? iii)Why is HCl a strong acid than acetic acid?

Answer 1

i) Solution A is acidic and Solution B is basic.
(since in pH scale,1-6 signifies acidic substance,7 signifies neutral,8-15 signifies basic/alkaline)

ii) Solution A has more H+ - ion concentration.

iii) HCl is a stronger acid than Acetic Acid because HCl dissociates completely on dissociation but Acetic Acid either dissociates partially or doesn't dissociate at all.
