Bronsted acid and base? (did i get the spelling right?)?

Question

can you teach me how to identify the conjugate acid and conjugate base in the eq?

HC2H3O2 + H2O <--> H3O + C2H3O2

and can you teach me how to get the parent acid of HSO4 and HS, NH3 and NH2?

i didnt understand all of these in our class discussion. please help :((

Answer 1

A Brønsted acid is capable of donating a proton, whereas a Brønsted base can pick up a proton.

The difference between an acid and its conjugate base, or a base and its conjugate acid, is one proton (H ion). In the above example, H2O and H3O+ differ by one proton, so they form a conjugate pair. The H2O has picked up a proton to form H3O+, so H2O is the base and H3O+ the conjugate acid.

Because there are always 2 pairs, CH3COOH is the acid and CH3COO- its conjugate base.

To get the parent acids of these 4 bases, add a hydrogen. HSO4 is the conjugate base of H2SO4, sulfuric acid. Do the same for the other 3.

Answer 2

H30+ is the most acid compound in the world, so this is the acid conjugate so, and of course, the corrisponding base is H2O.

Ossalic acid C2H4O2 is obviously an acid, who&#039;s conjugated with the base C2H3O2-

You have to put an hydrogen in all that compounds to get the parents acids
