Combining Cations & Anions to Name Ionic Compounds

In this video, Kevin Tolkoff explains how to write chemical formulas for various compounds. He provides detailed examples, including calcium chloride, aluminum sulfate, aluminum phosphate, sodium nitride, and ferric perchlorate. The video emphasizes understanding ion charges and using them to determine the correct chemical formula. It also highlights the importance of writing ions first for partial credit in exams.

How do you derive the final formula for sodium nitride?

What is the charge of ferric ion and how does it affect the formula for ferric perchlorate?

Discuss the importance of knowing the charges of individual ions when writing chemical formulas.
