 why is copper nitrate written as Cu(NO3)2 instead of CuNO3 when the valency of copper is +1 i.e why do we use the (II) valency of copper(+2) only in formula  of copper nitrate?

 copper can be classified into two,cupprous and cupric.cupprus has valency no:1 and cuppric has valency 2.cuppric is taken as the common copper.so we use cuppric valency to mention copper..that means we take valency of cuppric as the valency of copper..


thumbs up plzz..
