Iron sulfate, iron sulfate.
00:08
So the individual ions of iron sulfate are fe3 +, and so4 2-.
00:18
And while writing the chemical formula we know that the charges present on the individual ions are exchanged between them.
00:26
Like the charge on the sulfur will come to fe side and the charge present on the fe will go to so4 side.
00:35
So it will be equals to fe2so4 or 4.
00:38
So we can say that the atomicity of fe is the charge present on the so4 and the atomicity of so4 is the charge present on the fe.
00:50
So the final formula is fe2so4 4.
00:54
So now we have calcium iodide.
00:59
So like iron sulfate we can also write the chemical formula for calcium iodide.
01:06
So the individual ions are ca2 +, and i-.
01:10
So it will exchange so it will be equals to cai2.
01:14
Then we have tin dichromate.
01:22
So tin is sn4 +, and dichromate is cr2o7 2-.
01:32
So it will equals to like the chemical formula will be sn2cr2o7 4.
01:40
But we can simplify it.
01:41
So after simplifying we will get the formula sncr2o7 2.
01:49
So this is the right chemical formula of tin dichromate.
01:53
Then we have silver nitrate.
01:56
So we have silver nitrate.
02:00
Silver.
02:02
So silver nitrate the individual ions are ag +, and no2-.
02:10
So the formula will be agno2.
02:15
This is silver nitrate.
02:17
Then we have copper acetate.
02:21
Copper acetate.
02:25
So copper is cu2 +, and acetate is cs3coo-.
02:33
So the chemical formula will be cucs3coo 4...
