Diffusion of sulfuric acid in aqueous solution has been measured by a conductimetric technique at 25 °C over the concentration range from 0.00035 to 0.2 mol dm−3. At the lower end of this range, dissociation of bisulfate to sulfate and hydrogen ions produces a sharp increase in the rate of diffusion of the sulfuric acid component. Expressions are …

Sulfuric acid is a very strong acid; in aqueous solutions it ionizes completely to form hydronium ions (H 3 O +) and hydrogen sulfate ions (HSO 4 −). In dilute solutions the hydrogen sulfate ions also dissociate, forming more hydronium ions and …

However, do take note that they are in fact heavily solvated in aqueous solution. In some textbooks, it may be said that for the electrolysis of dilute H2SO4 H 2 S O 4, the oxidation half-equation is written as 2HX+ +2eX− HX2 2 H X + + 2 e X − H X 2 and the reduction half-equation is written as 4OHX− 2HX2O +OX2 +4eX− 4 O H X − 2 H X 2 ...

The first acid dissociation constant of "sulfurous acid" in aqueous solution is therefore defined as: ... Although sulfuric acid is a strong acid, sulfurous acid is weak. Pauling provided a way of systematizing the inductive effect by …

The balanced chemical equation is as follows: 2CH3CH2CO2H(aq) + Ca(OH)2(aq) → (CH3CH2CO2)2Ca(aq) + 2H2O(l) The reaction of a weak acid and a strong base will go to completion, so it is reasonable to prepare calcium propionate by mixing solutions of propionic acid and calcium hydroxide in a 2:1 mole ratio.

To explore the feasibility of controlling S(IV) chain oxidation to sulfuric acid in liquid hydrometeors, the effect of radical scavenging on each SO x •-radical (x = 3, 4, 5) was simulated. The results show that for the SO 5 •-radical a scavenger reactivity of ∼100 s-1 may be enough to reduce the chain length by >98%.
