Chlorine forms a number of oxyacids. Which of the following is the correct order of increasing acid strength ... 

Arrange the following oxyacids in order of decreasing acid strength. 

What products form when disubstituted sodium and ammonium-sodium orthophosphates are roasted What orthophosphates are used as fertilizers Compare the strength of the oxyacids of phosphorus, sulphur, and chlorine, and also of nitrogen and phosphorus. 

Hydrogen sulphide is the weakest acid, di- and tri-thionic acids are approximately of equal strength, whilst sulphurous acid is the weakest oxyacid in the list.1... 

More important for inorganic oxyacids is the number of oxygen atoms surrounding the central atom. Thus in the series of chlorine oxyacids. acid strength increases in the order HOCI < HOClO < H0C102 <- HOClOj. The trends in acidity of oxyacids, and even reasonably accurate predictions of their pKu values, can be obtained from 19... 

Low-temperature CO adsorption measurements indicate that the strength of Bronsted acid sites on reduced catalysts are lower than those characteristic of the oxidized catalyst.27 This finding is not unexpected, as it is well known that the acid strength of inorganic oxyacids depends on the oxidation state of the central atom.30... 

Trifluoroacetic acid is a nonoxidizing acid whose aqueous solutions are comparable in strength with those of the mineral acids 115), but as a bulk solvent it is weakly acidic and does not even protonate water (236). Trifluoroacetic acid is also weakly basic and is a nonelectrolyte in 100% sulfuric acid (21). One of the major difficulties of using pure trifluoroacetic acid is its remarkable affinity for water and, to maintain an anhydrous medium, a small quantity of trifluoroacetic anhydride is usually added. This affinity for water is so pronounced that trifluoroacetic acid will dehydrate oxyacids and, for example, converts sulfuric acid into polysulfuric acid. 

The adsorption of anions of weak oxyacids indicates a Lewis acid character of the Ft surface. The tendency of the metal to attract electrons, in particular in the case of Pt(l 11), is reflected in several facts. Thus anions of weak acids tend to dissociate on the surface, indicating that the strength of the adsorbed acids is enhanced by the metal. Furthermore, the anions seem to transfer their charge to a great extent, at least in the case of adsorption at Pt(lll), as demonstrated by the experiment of Orts et al. [154] and indirectly confirmed by the high degrees of coverage reached by adsorbed sulfate ions on this surface. 

In the series of oxyacids of chlorine, the acid strength in aqueous solution is in the order HCIO4 > HCIO3 > HCIO2 > HOCl...
