Understanding Titanium Compounds and Ions

The video tutorial explains how to write the formula for titanium IV oxide, also known as titanium dioxide. It begins by introducing the chemical symbols for titanium and oxygen, and explains the significance of the Roman numeral IV, indicating a 4+ charge for titanium. The video then discusses the charge of oxygen, which is 2-, and demonstrates how to balance these charges to achieve a neutral compound. The tutorial also covers the common name 'titanium dioxide' and explains its meaning. The video concludes with a summary of the formula and a thank you to viewers.
