Question

Five solutions a b c d and e when tested with universal indicator showed pH is 4,1 ,11, 7 and 9 respectively classify the solutions are as given below
a. neutral
b. strongly alkaline
c. strongly acidic
d. weakly acidic
e. weakly alkaline​

Answer 1

Answer:

B→ Strongly Acidic

A→ Weakly Acidic

D→ Neutral [pH=7]

E→ Weakly Alkaline

C→ Strongly Alkaline

Answer 2

In increasing order of hydrogen ion concentration:

$\small\mathrm\purple{pH 11(B) -> pH 9(E) -> pH 7(A) -> pH 4(D) -> pH 1 (B)}$

PH11 – Strongly alkaline

pH9 – weakly alkaline

PH7 – Neutral

pH4 – Weakly acidic

pH1 – Strongly acidic
