Why is copper Sulphate also written as copper II 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.
What is the formula for potassium sulphate?
Valency of k=1+ valency so4=2- after crisscrossing the valencies, we get- chemical formula- k2so4
What charge is copper 2 solphide?
Copper II sulphate has variable valency properties, which translates to variable charges.
How do you take out valency an element?
Group number 1 = Valency 1+group number 2 = valency 2+group number 3 = valency 3+group number 4 = valency 4+ and 4- (some cases) group number 5 = valency 3-group number 6 = valency 2-group number 7 = valency 1-group number 8 = valency 0For the transition elements they will either state Copper (III) Sulphate or it will be like Cu2(SO4)3You can find the valency by the base of sulphate and you know its positive because metals are always positive and are written in the left.Source: I am a GCE O Level Sciences Student (O2)
