This focused worksheet is designed to help students master acid-base concepts through pH and pOH calculations. It includes practice on hydrogen ion [H₃O⁺] and hydroxide ion [OH⁻] concentrations, completing data tables, and determining whether solutions are acidic, basic, or neutral. Students will develop their problem-solving skills by working through real calculation scenarios and understanding the relationships between pH, pOH, and ion concentrations. The worksheet also includes application qu
