Overview / Purpose / Essential Questions
Performance / Lesson Objective(s)
There are many household substances including cleaners and foods that are either acidic or basic based. This lesson will give students an understanding of what they are and how they can be classified in chemistry.
We will use a universal indicator which is a pH indicator that easily shows color transitions over a pH value ranges from 1-14 to determine whether an aqueous solution of interest are acidic, basic or neutral.
Wrap up / Conclusion
Students will be able to see the transition of color from red indicating highly acidic solution to orange-yellow color as the solution approaches neutral pH with color green. As solutions become more basic the color transition from green to blue and then approaches bright violet color for highly basic solutions. Therefore, test solutions can be grouped into acidic, neutral or basic based solutions.
Is there a trend among food samples and other solutions?
