Question

Quizplus · Accepted Answer

Polyamines are positively charged when the pH is near neutral. This is because they contain multiple amine groups (NH2) which can be protonated (pick up a hydrogen ion) and become positively charged in acidic conditions. When the pH is near neutral, these groups are not protonated, but still carry a positive charge due to the presence of the amine groups.
