Formula of the compound barium hydroxide?

Answer 1

Ba+2 OH-1 <--- these are the ions and their charges

Ba+2 OH-1 OH-1 <--- the charges have to add up to zero, so one +2 barium ion cancels out two -1 hydroxide ions

Ba(OH)2 <--- simplify

Answer 2

Ba(OH)2

Though barium hydroxide is a base, not an acid.

Answer 3

Barium's ionic charge is +2.

Hydroxide's change is -1.

To balance out we need two hydroxides for one barium.

So:

Ba(OH)2

Answer 4

The chemical formula of barium hydroxide is Ba(OH)2. It consists of one barium ion (Ba2+) and two hydroxide ions (OH-) held together by ionic bonds.

Answer 5

the formula is Ba(OH)2

Answer 6

Formula: Ba(OH)2

Answer 7

Ba(OH)2
