What are cation and anion exchange resins?

Anion resins and cation resins are the two most common resins used in the ion exchange process. The difference between anion and cation resins is that one is positively charged (anion) and the other is negatively charged (cation). cation resins, which attract positive ions with their negative charge.

What are cationic and anionic resins?

A cation resin is one that exchanges positive ions. An anion is an ion with a negative charge. Common anions include Cl-1, SO4-2, and OH-1 . An anion resin is one that exchanges negative ions.

What is the difference between cation and anion resin?

The main difference between cation and anion resins is that one is positively charged (cation) and the other is negatively charged (anion). This makes them useful in removing different types of contaminants (which will also vary depending on their size and chemical composition).

Which are anion exchange resins?

Anion exchange chromatography is a form of ion exchange chromatography where a negatively charged biomolecule binds to a positively charged resin.

How to write the formula for magnesium iodide?

Magnesium iodide is a binary ionic compound (so we’ll need to balance ionic charges). Write the element symbols for Magnesium and Iodine. Use the Periodic Table to find the ionic charges for Magnesium and Iodine.

What are the products of the dissociation of magnesium?

Explanation: Magnesium iodide is a soluble ionic compound that dissociates completely when dissolved in water to produce magnesium cations and iodide anions in aqueous solution. Now, magnesium is located in group 2 of the Periodic Table, which implies that magnesium atoms tend to lose 2 electrons and become cations that carry a 2+ charge.

What happens when magnesium iodide is dissolved in water?

Therefore, the chemical formula for magnesium iodide is [Mg2+] + 2[I−] → MgI2 You can now say that when magnesium iodide dissolves in water, it produces Mg2+ and I− ions. MgI2(aq) → Mg2+ (aq) +2I− (aq)

Which is a noble gas magnesium or iodine?

Magnesium comes from Group 2; as a metal it needs to lose 2 electrons to assume a Noble Gas configuration (that of neon); on the other hand iodine needs to gain 1 electron to assume the xenon configuration. The ion formation reflects this tendency. What is the formula of potassium oxide?
