Periodic acid (/ ˌ p ɜːr aɪ ˈ ɒ d ɪ k / per-eye-OD-ik) is the highest oxoacid of iodine, in which the iodine exists in oxidation state +7. It can exist in two forms: orthoperiodic acid, with the chemical formula H 5 IO 6, and metaperiodic acid, which has the formula HIO 4. Periodic acid was discovered by Heinrich Gustav Magnus and C. F ...
A monosaccharide with nine carbons. An example is sialic acid. Periodic acid: Periodic acid Or per-iodic acid, is pronounced / ˌ p ɜːr aɪ ˈ ɒ d ɪ k / PURR-eye-OD-ik and not * / ˌ p ɪər i ˈ ɒ d ɪ k / PEER-ee-OD-ik. It refers to one of two interconvertible species: HIO 4 (metaperiodic acid), or H 5 IO 6 (orthoperiodic acid
A mnemonic is a memory aid used to improve long-term memory and make the process of consolidation easier. Many chemistry aspects, rules, names of compounds, sequences of elements, their reactivity, etc., can be easily and efficiently memorized with the help of mnemonics.
Orthoperiodic acid, H 5 IO 6, is stable, and dehydrates at 100 °C in a vacuum to metaperiodic acid, HIO 4. Attempting to go further does not result in the nonexistent iodine heptoxide (I 2 O 7), but rather iodine pentoxide and oxygen. Periodic acid may be protonated by sulfuric acid to give the I(OH) + 6 cation, isoelectronic to Te(OH) 6 and ...

An example of the difference is the empirical formula for glucose, which is CH 2 O (ratio 1:2:1), while its molecular formula is C 6 H 12 O 6 (number of atoms 6:12:6). For water, both formulae are H 2 O. A molecular formula provides more information about a molecule than its empirical formula, but is more difficult to establish.
In cases where the carboxylate is not generally considered as a functional group, the plural may either redirect to the article about the parent acid (or the carboxylate if there is a separate article about the carboxylate), or be a separate article or chemistry index that lists salts and esters of the parent acid (e.g. benzoates). Rare cases ...
In organic chemistry, the Malaprade reaction or Malaprade oxidation is a glycol cleavage reaction in which a vicinal diol is oxidized by periodic acid or a periodate salt to give the corresponding carbonyl functional groups. [1] [2] The reaction was first reported by Léon Malaprade in 1928. [3] [4] Amino alcohols are also cleaved. [5]
