Question

four solutions a b c and d when tested with universal indicator showed ph is 2, 1,12 and 9 respectively which solution is strongly acidic weakly acidic strongly basic weakly basic​

Answer 1

Answer:

I think weakly acidic but I am not sure

Explanation:

if it is correct then please mark as brailiest and plz follow me

Answer 2

Answer:

(b) is strong acid--1

(a) is weaker than b--2

(c) is strong base--12

(d) is weaker than c--9

explanation:

THE SUBSTANCE IS ACIDIC IF ITS PH VALUE IS LESS THAN 7

THE SUBSTANCE IS BASIC IF ITS PH IS MORE THAN 7

THE SUBSTANCE IS NEUTRAL IF ITS OH IS 7 (H2O)
