Question

Which pairing matches the type of substance with the item it donates?

A acid: proton; base: electron pair
B acid: electron pair; base: proton
C acid: electron pair; base: H+ ion
D acid: H+ ion; base: proton

Answer 1

I think The answer is A

Answer 2

Answer: Option (A) is the correct answer.

Step-by-step explanation:

It is known that acids are the species that donate hydrogen ions (
`H^(+)`) or protons upon dissociation in an aqueous solution.

For example,
`HCl \rightarrow H^(+) + Cl^(-)`

Also, bases are the species which are electron rich and hence they donate electrons to an electron deficient atom.

For example,
`NH_(3)` is a base.

Therefore, we can conclude that out of the given options correct pairing is acid: proton; base: electron pair.
