the dots just mean that they are just linked with each other and can be separated through certain methods like MgSO4•7H2O can be separated by heating from water and it only means that they are just forming a complex.....

How they are linked with each other?
no its somewhat like multiplication just these dot represent they are just linked
linked through bonds
Which bonds?
sometimes its hydrogen bond of water and sometimes these are bonds of complexes
Actually you know one thing? I am beginner in learning about the elements and the compounds. I saw the formula for potash alum in my Science book and it was like this: K2SO4.Al2(SO4)3.24H2O . So, I just can't understand the presence of the dots.
The reason of the presence of the dots.
thats what i realised earlier actually I'm a 12th qualified student and i know what you really can't get......
thats what i explain you earlier you will clear your concept in upcoming classes
Okay. I think that I will clear this concept in my upcoming classes. Thank you for your advice.
