The video tutorial explains how to determine the oxidation number of gold in gold(III) nitrate. It begins by identifying the compound as neutral, meaning the oxidation numbers must sum to zero. The tutorial then discusses the oxidation numbers in ions, focusing on the nitrate ion with a -1 charge. By having three nitrate ions, the total negative charge is -3, requiring gold to have a +3 oxidation number to balance it out. The video concludes with a brief mention of additional resources for understanding nitrate ion oxidation numbers.
