Polymers with ionic functional groups have been developed for removal of ions from water.One example is Amberlite.One form of Amberlite has the structure shown below,where the -SO₃H groups act like a weak acid.What type of ions will this polymer attract?

Question

Quizplus · Accepted Answer

The -SO₃H functional groups act like a weak acid which means they can donate a proton (H+) to a water molecule and become negatively charged. This makes the polymer attract cations (positively charged ions) through electrostatic interactions, as opposites attract. Therefore, choice A is the best answer.
