hydroxyl ion Значение & определение

Примери за hydroxyl ion

• It forms a series with the more common hydroxylherderite, which has more hydroxyl ion than fluoride.

• Their hydrolysis occurs when the nucleophile (a nucleus-seeking agent, e.g., water or hydroxyl ion) attacks the carbon of the carbonyl group of the ester or amide.

• This applies in general: any equilibrium constant is equally valid for a product with an oxide ion as for the product with two hydroxyl ions.

• In an aqueous base, hydroxyl ions are better nucleophiles than polar molecules such as water.

• In alkaline solutions, nucleophilic hydroxyl ions attack the electrophilic central carbon to produce the colourless triphenylmethanol or carbinol form of the dye.

• Marked increases or decrease in conductance are associated with the changing concentrations of the two most highly conducting ionsthe hydrogen and hydroxyl ions.

• The positive hydronium ions that approach the negative cathode mostly combine with negative hydroxyl ions to form water.

• Photolysis of water vapor and carbon dioxide produces hydroxyl ions and atomic oxygen, respectively, and these in turn produce oxygen in small concentrations, with hydrogen escaping into space.
