ESTERS OF ARSENOUS AND ARSENIC ACIDS. Neutral esters of arsenous acid or arsenic acid, such as triorganyl arsenite and triorganyl arsenate, can be prepared, provided that the reaction products are protected from the action of moisture and acidic compounds. 745 The arsenic–oxygen–carbon bond also has considerable hydrolytic instability ...
Scheele's green (cupric arse- nite), whose formula has been reported to be Cu(As0212 and CuHAs03, is an example of an insoluble arsenite. Arsenic acid forms a corresponding series of salts that have similar solubility properties. Commercial lead arsenate, used as an insecticide, consists of PbHAsO4 and some Pb3(As0412.
Draw Bohr diagrams for the following: a potassium atom. a nitrogen atom. Identify how many valence electrons are present in each. Include the number of protons and neutrons in the nucleus. Compounds. Recall: A compound is a pure substance made up of two or more elements.
