There are given, 4 ions are given and we have to check which one is having incorrect ionic charge for most common ion.
00:12
Now let us see this is nitride ion, n3 minus, this is correct, n3 ion is most common, so it is correct.
00:26
Ca 2 plus ion, this is also correct, calcium generally forms 2 plus ion, sulfate, so4, so4 is actually 2 4.
00:35
Sulfur is having common ions, so42 minus this is sulfate ion.
00:43
So, this is the incorrect one.
00:46
Then i minus iodide ion.
00:49
Iodide ion, this is correct.
00:52
This is calcium ion correct...
