Question

You are given three solutions X, Y and Z with pH values 1, 9 and 13 respectively. Which solution has more hydrogen ion concentration among the three? State the nature 'acidic or basic' of each solution.​

Answer 1

Answer:

According to the theory on a pH scale, a more acidic substance is assigned a lower value. Normally substances with pH less than 7 are considered as acidic and those with pH greater than 7 are considered as basic with acidic strength increasing as we move towards 1 from 7 and the basic strength increases as we move toward 14 from 7. The more the acidic a substance is the more the hydrogen ions concentration.

Hence, in the given solutions, solution A has more hydrogen ions concentration as it is having the least pH value out of the three.

The nature of each solution is:

Solution A-acidic

Solution B- basic

Solution C- basic
