Feb 04, 2009· The "Roman numeral "IV" is the charge on titanium ion (+4). The charge on the hydroxide ion is "-1". Because the sum of all the charges in the formula has to be zero, we need to pair up one titanium "+4" ion with two hydroxide "-1" ions. Similarly, an oxide ion has a charge of "-2", so two of them must be paired up with one titanium +4 ion.
