The chlorite ion, or chlorine dioxide anion, is the halite with the chemical formula of ClO − 2.A chlorite (compound) is a compound that contains this group, with chlorine in the oxidation state of +3. 2 - Complete the table below. remember, that comes from the Roman numeral. 2 - Give the numbers of protons and neutrons in (a)... Ch. In a neutral compound, these charges would have to compensate each other, with the formula being Hg(ClO4)4 : +4 + 4*(-1) = 0 - but, again, I don't really think such a compound exists - mercury forms compounds in oxidation states of (I) and (II) only, under normal conditions. Experts are waiting 24/7 to provide step-by-step solutions in as fast as 30 minutes!*. Perchlorate occurs naturally in the environment, in deposits of nitrate and potash, and can be formed in the atmosphere and precipitate into soil and groundwater.

Concept Introduction: An ionic compound is composed of cation and anion. The perchlorate ion (ClO4 -) is very stable in water, and its salts are highly soluble in water. Here cation is positively charged and anion carries negative charge. 2 - How does Daltons atomic theory explain each of the... Ch. In addition, the agency requested comment on three alternative regulatory options: 1. If you know that a sufate ion is SO 4 2-then to get the formula for hydrogen sulfate ion, you add a hydrogen ion to the front of the formula. Median response time is 34 minutes and may be longer for new subjects. Further investigations are needed to have a better view of the different sources of contamination of food, in particular fruits and vegetables, with perchlorate. (b) Sodium perchlorate. ...
