Webhydroxide cycle operations. Cation resin stability also is dependent on pH; the stability to hydrolysis of the carbon-sulfur bond diminishes with a lowering of pH. They are much more stable than anions however and can be operated up to 150°C (300°F). Resin Structure and Manufacture The manufacture of ion exchange resins involves the ... WebExplanation: Consider the equilibrium R-OH ⇌ R+ + OH- conj. base of H2O Water is a weak acid, so the hydroxide ion is a strong base. It "wants" to use its lone pair electrons to form a covalent bond. Thus, the position of equilibrium lies far to the left. If we protonate the alcohol, we get R-+ OH2 ⇌ R+ + OH2 conj. base of H3O+ freezer cover
