Oxyacids acid strength

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... 

For oxyacids, acid strength increases with the electronegativity of the atoms bonded to the oxygen atom and also increases with the number of oxygen atoms in the molecule. 

Arrange the following oxyacids in order of decreasing acid strength. HCIO, HIO, HBrO, HC103, HC102... 

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. 

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... 

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

The acid strength of the oxyacids of chlorine in aqueous solution rank as HCIO4 > HCIO3 > HCIO2 > HOCl The pKa values of these acids are below. 

How does the acid strength of an oxyacid depend on (a) the electronegativity of the central atom (b) the number of non-protonated oxygen atoms in the molecule ... 

FIGURE 5.2.1.1 Lewis Diagrams of Oxyacids. The strength of the acid is related to the number of 0x0... 

We can summarize these ideas as two simple rules tiiat relate tire acid strength of oxyacids to tiie electronegativity of Y and to tiie number of groups attached to Y. 

For oxyacids that have the same number of OH groups and the same number of O atoms, acid strength inereases loith increasing electronegativity of the central atom Y. For example, the strength of the hypohalous acids, which have the structure H—O—Y, increases as the electronegativity of Y increases (Table 16.6 ). 

Table 22.3 summarizes the formulas of Ihe known oxyacids of the halogens and the way Ihey are named. (Section 2.8) The acid strengths of the oxyacids increase...
