23. Good job learners! Now, let’s validate if your answers are correct!

24. How did you identify the acidic samples in your activity? How did you identify the basic samples in your activity ?

25. What is the relationship between the result of your activity and the video clip presented? Acids- substances whose waters solution exhibits the following properties: turns litmus paper red, has sour taste, neutralizes bases and reacts with active metals and produce hydrogen gas. Base- substances whose water solution exhibits the following properties: turns litmus paper blue, has bitter tastes , has a soapy feeling and neutralizes acids.

26. Are the answers of the groups: MATHinik , MahuSCIENCE and MaARTi are correct? How can you say so? Indicator- a natural substance that is used to determine the acidity and basicity of a solution. Neutral solution- has a pH level of 7. pH- potential of hydrogen ion (H+), measures the acidity or basicity of a substance.

27. What can you say about the foods that you are consuming everyday? What is the most insightful learning you have learned in your activity? Why did you say so? How about in your households, what are the most important things to remember?
