On July 19, 2022, teacher Sotheavy Ry led the 9th graders of American Intercon School, Phsar Thmey Campus, to conduct a Chemistry experiment under the theme “Finding the Acid-base Cycle in Some Solutions”
Before the experiment, the teacher showed the experimental materials such as: lemon juice, glass cleaner, vinegar, lime juice, milk, salt water, purple cabbage, glass, resin, stove, pot, and pH device. It should also be noted that the objective of the experiments are to:
– Students create pointing units to detect the presence of base acids.
– Students learn to use pH devices to measure acid-base solutions.
– Students define the characteristics of each solution.
