Amides can be hydrolyzed to yield carboxylic acids. The conditions are much more severe than those for other carboxylic acid derivatives. Acidic hydrolysis occurs by addition of water to the protonated carbonyl, followed by proton transfer to make the nitrogen a better leaving group. The reactions are reversible, and the reaction is driven to completion by protonation of NH3 at the end. Draw curved arrows to show the movement of electrons in this step of the mechanism.

What is the ph of a solution that has a hydrogen ion concentration of 1.0 * 10 -9 m?

One way in which the useful metal copper is produced is by dissolving the mineral azurite, which contains copper(ii) carbonate, in concentrated sulfuric acid. the sulfuric acid reacts with the copper(ii) carbonate to produce a blue solution of copper(ii) sulfate. scrap iron is then added to this solution, and pure copper metal precipitates out because of the following chemical reaction: (s) (aq) (s) (aq) suppose an industrial quality-control chemist analyzes a sample from a copper processing plant in the following way. he adds powdered iron to a copper(ii) sulfate sample from the plant until no more copper will precipitate. he then washes, dries, and weighs the precipitate, and finds that it has a mass of .

The kw for water at 0 °c is 0.12× 10–14 m2. calculate the ph of a neutral aqueous solution at 0 °c.
