Question

How many acidic protons are there in each : - (I) CH3COOH - (ii) H2SO4 - (iii) Na2CO3 - (iv) Nahco3 - (v) H2CO3​

Answer 1

Answer:

(i) 1

(ii) 2

(iii) 0

(iv) 1

(v) 2

Explanation:

I assume you are aware of proton is $H^{+}$.

(i) Acetic Acid, n-factor=1, and moreover, Resonance between the $COO^{-}$delivers 1 proton, or$H^{+}$.

(ii) Sulphuric acid, n-factor=2.

(iii) Sodium Carbonate, no protons.

(iv) Sodium Hydrogen-carbonate delivers 1 proton in basic medium.

(v) Carbonic acid, although can deliver 2 protons, but is very happy to release only 1 at a time.
