Question

Give the name and formula of two (i) strong monobasic acids (ii) two weak dibasic acids

Answer 1

Strong monobasic acids are
1) Hydrochloric acid. (HCl)
2)Nitric acid (HNO3)

Weak dibasic acids
1)Oxalic acid (C2O4H2)
2)malonic acid (H2C3H2O4)

HOPE IT HELPS .....

Answer 2

acid is a substance which can donate a proton (protic hydrogen ions )or accept an electron pair.

and basicity is the number of hydrogen atoms replaceable by a base of an acid.

HA is general formula of monobasic acid.

similarly, H_2B is general formula of dibasic acid .

now come to the question,

(i) strong monobasic acid : basically, hydrogen halide acids are strong acids for example , hydrochloric acid (HCl), hydrogen fluoride (HF)

(ii)two weak dibasic acid : generally, organic acids are weak acids . for example. carbonic acid (H2CO3) , oxalic acid (H2C2O4)
