Understanding Permanganic Acid Properties

The video tutorial explains how to write the chemical formula for permanganic acid. It begins by identifying the components of the acid, noting that most acids start with hydrogen. The tutorial then explains the absence of a prefix, indicating the presence of a polyatomic ion. The instructor guides viewers through identifying the permanganate ion and replacing the 'ic' ending with 'ate'. Finally, the video demonstrates balancing the charges to complete the formula, resulting in HMnO4.

What is the first element typically found in the formula of an acid?
