Hi, what i'd like to know is, does BaOH exists?? or does it have to be Ba(OH)2???
any assistance would be greatly appreciated!!!
thank you!

Ba has +2 charge and OH has -1 charge
now combine these two radicals so that total  charge is zero
you can see one mole of Ba+2 needs two moles of OH-
Ba (OH)2
Did you get the presentations sent by me on chemical bonding?

thank you!!

so does that means that when you say barium hydroxide, the formula is really Ba(OH)2??

and yes, i got the slides. thank you very much!! i'm still in the process of going through it.

thank you!!!!11

yes Ba(OH)2
