What is the Difference Between Cationic and Anionic Polyelectrolyte?
🆚 Go to Comparative Table 🆚The main difference between cationic and anionic polyelectrolytes lies in their charges and structures in aqueous solutions.
Cationic polyelectrolytes have positively charged moieties and dissociate in aqueous solutions to give positively charged polyions or cations. They exhibit an extended structure in aqueous solutions. Cationic polyelectrolytes are attracted to anionic substances.
Anionic polyelectrolytes, on the other hand, have negatively charged moieties and dissociate in aqueous solutions to give negatively charged polyions or anions. They exhibit a collapsed structure in aqueous solutions. Anionic polyelectrolytes are attracted to cationic substances.
In summary, cationic polyelectrolytes have positive charges and extended structures, while anionic polyelectrolytes have negative charges and collapsed structures. These differences in charge and structure lead to variations in their applications and interactions with other substances.
Comparative Table: Cationic vs Anionic Polyelectrolyte
The main difference between cationic and anionic polyelectrolytes lies in the charges of their repeating units in aqueous solutions. Here is a comparison table highlighting their differences:
Cationic Polyelectrolytes | Anionic Polyelectrolytes |
---|---|
Positively charged repeating units | Negatively charged repeating units |
Dissociate in aqueous solutions to give positively charged ions | Dissociate in aqueous solutions to give negatively charged ions |
Attract negatively charged particles | Attract positively charged particles |
Polycations or cationic polyelectrolytes | Polyanions or anionic polyelectrolytes |
Extended structure in aqueous solutions | Collapsed structure in aqueous solutions |
Both cationic and anionic polyelectrolytes are used in various applications, such as water treatment, purification, and flocculation processes, to separate solids from water solutions.
