write the equation for the reaction of water with an alkyne in the presence of sulfuric acid and mercury (II) sulfate. describe keto-enol tautomerism. predict the structure of the ketone formed when a given alkyne reacts with sulfuric acid in the presence of mercury (II) sulfate.
Learning Objectives. By the end of this section, you will be able to: Predict whether a salt solution will be acidic, basic, or neutral. Calculate the concentrations of the various species in a salt solution. Describe the acid ionization of hydrated metal ions. Salts with Acidic Ions.
29 Αυγ 2023 · Most sulfates, including those of \(\ce{Na^{+}}\), \(\ce{K^{+}}\), and \(\ce{NH4^{+}}\), are soluble in water. Exceptions that are insoluble are white lead(II) sulfate and white barium sulfate: \[\ce{BaSO4(s) <=> Ba2+(aq) + SO42-(aq)} \nonumber \] with \(K_{sp} = 1.4 \times 10^{-8}\) \[\ce{PbSO4(s) <=> Pb2+(aq) + SO42-(aq)} \nonumber \]
13 Φεβ 2019 · The carbocation is now ready to be attacked by H 2 O to furnish an alkyloxonium ion because of stability and hyperconjugation. The final step can be observed by another water molecule attacking the proton on the alkyloxonium ion to furnish an alcohol. We see this mechanism below:
1 Ιαν 2021 · Water-soluble sulfates can penetrate to living organisms through water, or they can be reduced to sulfide (S 2−) under biological reduction reactions in aqueous solution media and then deposit in living organisms (Delisle and Schmidt, 1977).
In weathering or contact with aerated water, the sulfides are oxidized to yield sulfate ions which are carried off in the water. Sulfate is carried to bodies of water by rain and through solution of sulfate compounds in sedimentary geologic formations within the drainage basin.
1 Ιαν 1971 · Mechanisms and Mechanistic Criteria in Strong Acid Solutions Sulphuric acid/water mixtures may be regarded as a prototype of strongly acidic reaction media of high dielectric constant, and therefore much of the discussion that follows applies to acid-catalysed reactions in general.
