Question

YOU ARE GIVEN THREE SOLUTION A,BAND C WITH PH VALUE 2, 8 ,13 RESPECTIVELY WHICH SOLUTION HAS MORE HYDROGEN IONS CONCRATION AMONG THE THREE AND STATE THE NATURE OF EACH SOLUTION

Answer 1

Explanation:

Solution A ; pH value 2

solution B. ; pH value 8

solution C ;. pH value 13

We know that , lower is the pH scale , higher is hydronium ion or hydrogen ion concentration , more acidic is the solution.

So , solution A with pH value 2 has more hydrogen ion or hydronium concentration. It is acidic in nature and is a strong acid.

Solution B with pH value of 8 has More hydroxide ion concentration as compared to solution A. It is slightly alkaline in nature.

Solution C with pH value of 13 has more higher hydroxide ion concentration than both. It is highly basic or alkaline in nature.

...

Answer 2

Explanation:

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
