Valency of NO3 in CuNO3 is 1
its Cu(NO3)2 and valancy of nitrate is 1-
-2
Calcium Sulphate + Copper
no copper sulphate is not toxic it is flammable
does copper sulphate out a lighted splint
silicate, carbonate or sulphate
Copper(II) sulphate is written like this because here II denotes the oxidation state of copper or in simple language, it denotes its valency.Copper sometimes shows +1 valency and sometimes +2.So to specify, its valency in a compound, the valency is written in brackets.
Copper II sulphate has variable valency properties, which translates to variable charges.
The formula for a sulphate ion is SO42- so the valency of a sulphate ion is -2.
The valency of sulfur is 2.
Na2co3
H2so4-
The sulfate anion has a valency of 2-, i.e. it is SO4^2-
i think its 2
-2
magnesium has a valency of 2
Copper Sulphate mixed with hot water makes Copper Sulphate Crystals.
calcium + copper sulphate = calcium sulphate + copper hydroxide
