Glutamic acid is a naturally occurring α−amino that contains a carboxy group in its r group side chain. (glutamic acid is drawn in its neutral form with no charged atoms, a form that does not actually exist at any ph.) if the ph is gradually increased, what form of glutamic acid exists after one equivalent of base is added to the positively charged form? after two equivalents? after three equivalents?

answer: option (a) is the correct answer.

explanation:

the measurement of hydrogen ions in a solution is known as ph.

if ph of a solution is less than 7 then the solution is acidic. if ph of a solution is greater than 7 then the solution is basic.

when the ph of a solution equals 7, then the solution is considered as neutral.

the ph of pure water is 7, therefore, it means that concentration of hydronium ions equals that of hydroxide ions.
