For example – HCO3–-Bicarbonate or hydrogen carbonate Some polyatomic anions can be named as: Chemical Formula Polyatomic Anion NH2– Amide PO43- Phosphate CN– Cyanide Solved Examples Problem 1: In one molecule of the compound, determine how many atoms of every element are present for each ...
Considering that six electrons are needed to oxidize a bromide anion to a bromate anion (reaction 6), this charge should produce 0.02 moles of bromate anions at 100% faradaic efficiency and convert 2/3 (1 M) of the bromide anions in the initial electrolyte (20 ml of 1.5 M ...
For example, magnesium and bromine combine to form the ionic compound magne- sium bromide. Magnesium, a Group 2 metal, forms the Mg2+ cation. Note that the 2+ in Mg2+ is written as a superscript. Bromine, a halogen, forms the Br- anion when combined with a metal. In each formula ...
离子化合物的命名 (Names of ionic compounds) CuSO4 · 5H2O -copper (II) sulfate pentahydrate The number of cations and anions per formula need not be included in the compound name because anions have characteristic charges, and the charge of the cation has already been established by its name...

(a) General Formula 1 (where R1 is a C1 to C4 alkylene group, R2 to R4 are each a hydrogen atom or C22 or lower alkyl group that may have a substituent (two or three of R2 to R4 may not be hydrogen atoms), and X− is an anion of an inorganic acid or an organic acid); ...
Alternatively the oxidizing agent may be an alkali metal cation and complex anion of 3 to 4 0 atoms and an element in a high oxidation state, such as iodate, bromate, perchlorate, permanganate, chromate, molybdate, vanadate, arsenate and dichromate. The process may be carried out in a polar...
and A is an acid radical anion, preferably a polymerizable acid radical anion. In the above formula (1), examples of the organic group having a valence of n in R5is a group represented by formula: ##STR2## wherein n is an integer of from 2 to 6; and R6represents an organic group...
Most preferable is a compound in which A1 in the formula (I-1) is iodine atom. In the formulae (I-1) to (I-3), Z1n1− to Z3n3− represent, independently of each other, a counter anion. There is no special limitation on the kind of the counter anion. It may be a single...
1. An adsorbent composition consisting essentially of (i) about 5 to about 95% by weight of a hydrotalcite compound represented by the following formula (1) (M2+)xAl2(OH)2x+6-ny (An-)y.mH2O (1) wherein M2+ represents Mg2+ and/or Zn2+, An- represents an anion having a valence ...
