Chlorine and Hydrochloric Acid Concepts

The video tutorial explains how to write the formula for hydrochloric acid (HCl). It begins by identifying the rules for acids starting with 'hydro' and ending with 'ic'. The tutorial then identifies the elements involved, hydrogen and chlorine, and their respective charges. Finally, it demonstrates how to balance these charges to achieve a neutral compound, resulting in the formula HCl.

What is the significance of the prefix 'hydro' in naming acids?

• It shows the acid is a base.

• It means the acid is organic.
