Amberlite^® IR-120 Plus (H) (CAS 9002-23-7)

Amberlite® IR-120 Plus (H) is a strongly acidic, gel-type cation exchange resin utilized extensively in research and industrial settings for its ability to effectively exchange ions in aqueous solutions. Composed of a styrene-divinylbenzene copolymer matrix with sulfonic acid functional groups, this resin operates primarily through a mechanism of ion exchange, where it swaps its hydrogen ions (protons) for other positively charged ions (cations) in the solution. This exchange is driven by ionic concentration gradients, adhering to principles of chemical equilibrium. The "H" designation indicates that the resin is in the hydrogen form, facilitating efficient proton exchange critical for applications like water softening, where it mitigates water hardness by replacing calcium and magnesium ions with hydrogen ions. In research, Amberlite® IR-120 Plus (H) is pivotal for studies involving ion exchange kinetics, water quality analysis, and the preparation of solutions with specific ionic strengths or pH levels by selectively removing cations, thus ensuring controlled experimental conditions. Its robust ion exchange capacity and stability make it indispensable in settings requiring precise manipulation of ionic environments, such as in environmental testing and the synthesis of specialty chemicals.
