Question

define universal indicator you are provided with 4 solutions a b c and d the pH of the solution is 4b is 10c is 13 and D7 identify the most acidic and most basic solution arranged above for solutions in the increasing order of SPH in ion concentration​

Answer 1

Answer:

pH scale is used to know whether a compound is a base, an acid or a neutral compound and it's extent of acidity or basicity.

All the compounds that have pH range below 7 are acids (eg.HCl,H

2

SO

4

) and the compounds which have pH value above 7 are bases (eg.NaOH,KOH).

The compounds with pH value 7 are neutral eg.H

2

O,NaCl.

Hence, the correct answer is option (C).
