Lab Report 14:CHEM 106. Acids and Bases are pHun. Lab Report 14. CHEM 106: Acids and Bases are pHun Introduction: One of the ways we categorize solutions in chemistry is by dividing them into two groups; acids and bases. Acids are substances which donate Hydronium (H3O + ) ions in aqueous solution and have a pH under 7. Bases will produce hydroxide (OH- ) ions in aqueous solution and have a pH over 7. When acids and bases of relatively equal strength react with each other they can prod...
