By the use of ion-exchange resins
Basic resins exchange their OH - ions with the other anions such as HCO 3 - , Cl - , SO 4 2 - , present in hard water. Basic resins, therefore, are also known as acid exchange resins. Fig: 11.5 - Ion-exchange process for water so..

In an atom, the electrons present in various orbitals of the same subshell tend to exchange their positions which is associated with very small amount of energy. Half-filled and completely filled subshell configurations allow maximum exchange of electrons to take place. Therefo..
Zeolites - Shape-Selective Catalysis by Zeolites
>Zeolites as ion-exchange materials have been replaced by synthetic cationic and anionic exchange resins, but their use as selective adsorbents for gases or liquids is extensive. The zeolites act as molecular sieves for the reactants. To achieve this, zeolite..
Regeneration
After some time, the resins require regeneration as they become ineffective. Adding a strong acid regenerates acid resin and the basic resin is regenerated by treating it with a solution of a strong base. The regenerated resins are washed to remove Ca ..

Really liked thier styling of tutoring. Very helpful. they went step by step and had me work out the answer- Adad
When ever i visit TutorVista, I always leave with a good understanding of what they are teaching me, you guys are wonderful - Anna
I need tutoring from tutorvista till th end of my schooling. Tutors are not only experts they are brilliant enough to make a student like me understand the concepts of differentiation and functions.
She should be the head of Tutor Vista. She knows how to treat her students. Her teaching style is spectacular.
