Question

5 solutions A,B,C,D, and E when tested with universal indicators showed pH as 4,10,1,11 and 7 respectively with solution is
a) Neutral
b) Acidic
c) Basic
d) strongly acid
e) strongly base
f) weak acid
g) weak base
explain ( for 3 marks )​

Answer 1

Explanation:

a) D is neutral, as its pH value is equal to 7

b) C is strongly alkaline, as its pH value is 11.

c) B is strongly acidic, as its pH value is equal to 1

d) A is weakly acidic, as its pH value is equal to 4 and more than solution B.

e) E is weakly alkaline, as its pH value is equal to 9 and less than C.

pH value of the given solution in increasing order of hydrogen-ion concentration: 11<9<7<4<1

Answer 2

Answer:

A. acidic bcoz ph less

B.basic bcoz ph more than seven

C.strongly acid pH very less

D.strongly basic pH more than seven

E. and E is neutral bcoz on this pH value solution is neutral (pH -7)
