Five solutions A, B, C, D and E when tested with universal indicator showed pH as 4, 1, 11, 7 and 9 respectively. Which solution is
Arrange the pH in increasing order of hydrogen ion concentration ?
pH scale is a numeric scale which is used to determine whether an element is acid, base or neutral.
pH value less than 7 stands for acid.
pH value 7 stands for neutral.
pH value above 7 stands for base.
(a) Neutral : D solution
(b) Strongly Alkaline : C solution
(c) Strongly Acidic : B solution
(d) Weakly Acidic : A solution
(e) Weakly Alkaline : E solution
Increasing order of hydrogen ion concentration:
ie, C < E < D < A < B
