Arrhenius Theory

This word search centers on the Arrhenius definition of acids and bases. Acids are defined as substances that release *hydrogen ions* (H⁺), while bases release *hydroxide ions* (OH⁻). The vocabulary introduces key terms like *dissolve*, *release*, and *solution*. This theory serves as one of the foundational models for acid-base chemistry.

Students expand their understanding of historical models in chemistry and how they differ from modern ones. The puzzle builds knowledge of terminology related to ionic dissociation and water-based reactions. It encourages clarity around how substances behave in aqueous solutions. This is an excellent activity for reinforcing scientific definitions and distinctions.
