Question

how does the action of washing soda differ from that of ion exchange resins?​

Answer 1

Answer:

Addition of washing soda to hard water initiates a precipitation reaction in which the calcium ions are removed. On the contrary, ion exchange resin acts by replacing calcium ions in hard water with sodium ions when the hard water is passed through the ion-exchange resin in a column.

Answer:

On the contrary, ion exchange resin acts by replacing calcium ions in hard water with sodium ions when the hard water is passed through the ion-exchange resin in a column.

Ion-exchange chromatography resins have charged functional groups bound to resin beads which attract biomolecules of the opposite charge.

Strong exchangers do not vary and remain fully charged over a broad pH range, which can make optimization of separation simpler than with weak exchangers.
