I decided to research compounds with arsenic(As)in it and one cool kind of cool called Calcuim(C) and Arsenate(AsO4). Arsenate is a polyatomic compound which is arsenic(As) and oxygen(O). So the giving formula is Calcium(C) and arsenate(AsO4). Combined it’s Ca3(AsO4)2 because there is 3 calcium atoms and 2 arsenate atoms. The properties of the compound Calcium Arsenate (Ca3(AsO4)2) is the melting point is 2651 *F. The Vapor pressure is 0 mm. The specific gravity is about 3.62. Calcium Arsenate or Ca3(AsO4)2 doesn’t boil it decomposes. It also is a colourless compound it looks like a white powder. The molar mass is 398.072 g/mol. It is mainly used for the protection of cotton crops.

Some of my questions

1.) I read that Ca3(AsO4)2 is very toxic. What happens when Calcium Arsenate touches human flesh?

2.) Also I know that calcium(Ca) is a metal and arsenic(As) is a non-metal so what is the Ca3(AsO4)2 Calcium Arsenate?
