Lysine has the side chain (C H 2) 4 N H 3 plus. The alpha amino group is protonated and positively charged. The alpha carboxylic acid group is protonated and neutral. At what pH would the structure be the predominant ionization state? Consider the ionization state of all three of the functional groups.

answer is a

explanation:

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).
