So here we have to tell the formula of compound formed by the given ions.
00:13
So here the first case, cation is an a plus and the anion is so4 to negative.
00:21
So the formula would be n .a .2, so4.
00:25
Here, in the next case, we have zn2 plus and co3 to negative.
00:31
So the compound formula would be zn, co3.
00:35
Then we have nh4 plus and so4 -2 negative.
00:42
So the compound formula would be nh4 whole twice, so -4.
00:47
Then here we have al3 plus and cl negative.
00:53
So the compound formula would be alcl3.
00:56
Then here we have ca2 plus and p3 negative...
