Question

Polyamines are ________ charged when the pH is near neutral.
A) not
B) negatively
C) positively
D) super
E) randomly

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.
