What is the valency for plumbic?
The valency for plumbic is +4. This means that plumbic compounds typically have a charge of +4.
What is the valency of bromide ion?
The valency of bromide ion (Br-) is -1.
How to find valency of PO4?
PO4^-3 is an ion.So its valency is -3
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)
When the valency of calcium is 2 plus and the valency of carbide is 4- how does calcium carbide get the formula CaC2?
CaO + 3C >> CaC2 + COThis reaction can not be produced at a normal temperature achieved by combustion, but in an electric arc furnace. I can find out no more than that.Added:because the 'valency' of carbide is NOT uniqely -4: Actually in metal salts it's ion is (C2)2- , so with Ca2+ it forms CaC2The structural formule is not C-Ca-C but -Ca-(C=C)- formed in a chain with a triple bond between the Carbon atoms: ..... -Ca-C---C-Ca-C---C-Ca-..... etc.Even in ethyn H2C2 it is considered to have a -2 valency, though this is not a ionic (metal) salt.

What the valency for silver?
The valency of silver is typically +1. However, silver can also exhibit a valency of +2 in certain compounds.
What is the valency of Ferricyanide?
The valency of ferricyanide is -3. It contains one iron (III) cation with a valency of +3 and one cyanide anion with a valency of -1.
What is the Valency of sulfur?
The valency of sulfur is 2-. The valency of sulfur is 2-. The valency of sulfur (S) is +2
What is Valency of potassium dicromate?
The valency of potassium dichromate is +6. This is because potassium has a valency of +1, and each chromium atom in the dichromate ion has a valency of +6.
