what is the metal ion formula for
BaCL2 (times) 2H2O
it is not times. Water of hydration (look that term up) is attached
The name is barium chloride dihydrate
Your question does make sense to me.
it has a Bacl2 then a dot in the middle then 2h2o
To determine the metal ion formula for BaCl2 · 2H2O, we first need to identify the metal ion present in the compound. In this case, the metal ion is barium (Ba).
The formula BaCl2 indicates that there are two chloride ions (Cl-) associated with one barium ion (Ba2+). The presence of the · 2H2O indicates that there are two water molecules (H2O) associated with the compound.
To represent this compound using metal ion formula, we can write it as [Ba(H2O)2]2+ + 2Cl-. This indicates that the barium ion is coordinated with two water molecules, and there are two chloride ions associated with the compound. The charge of the barium ion is +2, while the chloride ion carries a charge of -1.
