This video tutorial explains how to determine the oxidation number of tin in tin(IV) bromide (SnBr4). It begins by introducing the concept of oxidation numbers and the neutrality of compounds. The video then discusses tin as a transition metal and bromine's typical oxidation state. It proceeds to calculate the oxidation numbers, showing that bromine has a -1 oxidation state, and with four bromine atoms, the total is -4. Therefore, tin must have a +4 oxidation state to balance the compound to zero. The video concludes by summarizing the findings.
