Introduction to Acids and Bases

Explore acids and bases! Learn their pH, properties, and definitions with this intro worksheet.

What Are Acids & Bases? Watch the video and answer questions on your paper. Acids and Bases Video Which statement is NOT true? Bases have a pH lower than 7. Bases release OH- ions. Acids release H+ ions. Lemon juice is acidic How did Svante Arrhenius define acids and bases? Acids have a pH above 7 and baseshave a pH below 7. Acids release H+ ions and bases releaseOH- ions. Acids release OH- ions and basesrelease H+ ions. Acids taste bitter and bases taste sour. Which is NOT true about the pH scale? The pH scale measures acids and basesfrom 1 to 14 on a scale. The pH scale focuses on the concentrationsof H+ and OH- ions in a solution. The pH scale was invented by SvanteArrhenius. A very strong acid would have a pHreading close to 1. An unknown solution has a pH reading of 8.4. Which statement is true about this solution? The solution is a strong acid. The solution is a weak acid. The solution is a strong base. The solution is a weak base. Perform the interactive lab linked here (you must enable flash): refer to the following information: sort the terms.
