Weak Acid Cation Resin

weak acid cation resin weak acid cation resin

Weak Acids
A weak acid only partially dissociates in water to give H+ and the anion. Examples of weak acids include hydrofluoric acid, HF, and acetic acid, CH3COOH. Weak acids include:
• Molecules that contain an ionizable proton. A molecule wih a formula starting with H usually is an acid.
• Organic acids containing one or more carboxyl group, -COOH. The H is ionizable.
• Anions with an ionizable proton. (e.g., HSO4- --> H+ + SO42-)
• Cations
• transition metal cations
• heavy metal cations with high charge
• NH4+ dissociates into NH3 + H+
