Perchloric Acid HCIO

Periodic acid has the normal formula HglO, with an octahedral arrangement of the oxygen atoms around the iodine atom, as shown in Figure 13-6. This difference in composition from its analog perchloric acid, HCIO, results, ... 

When comparing acids where X is bonded to additional oxygen molecules (for instance, comparing perchloric acid, HCIO, to chloric acid, I It IO,). the more additional oxygen atoms that are bonded to X, the stronger the acid will be (HCIO is stronger than HCIO,). 

Chromium analysis can be performed on the ash sample from leather or can be perfonned on the leather directly. ASTM D2807 is a method for testing chromium by leather digestion (ASTM D 2807-1998). In this method, weigh 1 g of leather to the nearest 0.0001 g and cut it into small pieces 0.5 cm in diameter. Transfer the specimen to a 250 ml flask and add sequentially 20 ml of concentrated nitric acid (HNOj), 15 ml of perchloric acid (HCIO ) and 10 ml of sulphuric acid (H. SOj. 

Perchloric Acid—HCIO —100.6—is the most stable of the series. It is cbtaiued by boiling potassium chlorate with hydrofluosilicic acid, decanting the cold duid. evaporating until white fumes appear, decanting from time to time, and hnally distilling. It is a colorless, oily liquid sp. gr. 1.782 which explodes on contact with organic substances or charcoal... 

Along with the three strong acids emphasized in the chapter (HCl, HNO3, and H2SO4), hydrobro-mic acid, HBr, and perchloric acid, HCIO, are also strong acids. Write equations for the dissociation of each of these additional strong acids in water. 

Yang and coworkers reported an electrochemical method to control the surface and bulk compositions, size, and morphology of Ag-Pt heterogeneous nanostructures by potential cycle in perchloric acid (HCIO ) aqueous solution (Fig. 2.14) [61]. When the PtigAg nanoparticles were treated at 0.6V or lower, which is below the... 

Perchloric acid, HCIO oq), Is another strong acid. 

Benzene reacts with mercuric acetate to give phenylmercuric acetate using perchloric acid (HCIO ) as a catalyst. What is the electrophile How does it form ...
