What are false cations in chemistry? Will mark brainliest.
Answers
Answer:
Cation, atom or group of atoms that bears a positive electric charge. See ion. Read More on This Topic. ion. Positively charged ions are called cations; negatively charged ions, anions.
Answer:
The ion - exchange resins are synthetic organic polymers (e.g., polystyrene).
These polymers contain exchangeable cations or anions.
In cation exchange resin, sodium ions are exchanged by calcium and magnesium ions from hard water. Thus, helps in softening of water.
Example :- zeolites alumino-silicate polymer with exchangeable sodium ions :
2NaAlSi
2
O
6
+Ca
2+
→Ca(AlSi
2
O

)
2
+2Na
+
The hardness is thus removed.
Similarly, anion exchange resins have exchangeable anions including Cl

An anion resin is one that exchanges negative ions.
