This project was preformed to supply Libretext authors with videos on General Chemistry topics which can be used to enhance their projects. Also, these videos are meant to act as a learning resource for all General Chemistry students.

Video Topics

This video discusses the different definitions of acids and bases used in chemistry.

Arrhenius Theory of acids and bases

Acids increases {H⁺} when dissolved in water. H⁺ is called a hydrogen ion or proton.

Bases increases {^-OH} when dissolved in water. ^-OH is called the hydroxide ion

This theory has problems because it neglects NH₃ as a base and does not consider the solvent H₂O.

Brøsted-Lowry theory of acids and bases

Acid: Proton donor

Base: Proton acceptor

Lewis Definition of acids and bases

Lewis Acid = Accepts an electron pair to form a bond

Lewis Base = Donates an electron pair to form a bond
