The video tutorial explains how to balance a chemical equation involving strontium hydroxide and acetic acid. It begins by counting the atoms on both sides of the equation, focusing on strontium, oxygen, hydrogen, and carbon atoms. The tutorial then demonstrates how to balance the equation by adjusting coefficients, particularly for acetic acid and water, to ensure equal numbers of each type of atom on both sides. The key takeaway is the importance of careful counting and adjustment to achieve a balanced equation.
