Explain why the water obtained after passing hard water through cation exchange resins is acidic.

Deionised water is obtained by passing hard water through

Will the water obtained by passing hard water through anion exchange resin, form lather with soap? Why ?

pH of the water coming out of cation exchange resin

Water obtained by purification with organic ion exchange resins is

Water obtained by purification of organic ion exchange resins is :

When any solution passess through a cation exchange resin that is in acidic form, H ion of the resin is replaced by cations of the solution. A solution containing 0.319 g of an isomer with molecular formula CrCl_(3).6H_(2)O is passed through a cation exchange resin in acidic form. The eluted solution requires 19 cm^(3) fo 0.125 N NaOH. The isomer is
