EQUIPMENT AND MATERIAL • • • AMMONIA LITMUS PAPER BEAKER GLASS 100 ML ORANGE JUICE WATER

PROCEDURE 1. Prepare some kind of solution in the beaker glass with the: a. orange juice b. ammonia c. water 2. Immerse blue litmus paper into each solution? 3. Observe what will happen the change of the blue litmus paper ! 4. Write the color change of the litmus paper on the table? 5. Repeat the procedure point 1 up to point 3 by using the red litmus paper 6. Write the color change of the litmus paper on the table?

The table of litmus paper color changes Litmus paper Orange juice ammonia water Red blue

Table change of litmus paper The table of litmus paper color changes colour Litmus paper Orange juice ammonia water Red blue red Blue blue

ANALYSIS • Is there any litmus paper color change when the blue litmus paper is immersed into the orange juice? • Is there any litmus paper color change when the blue litmus paper is immersed into the ammonia? • Is there any litmus paper color change when the blue litmus paper is immersed in to the water?

CONCLUSION 1. If the blue litmus paper is immersed into the orange juice, the color of the litmus paper will change from blue to red 2. If the blue litmus paper is immersed into the ammonia, the color of the litmus paper will not change 3. If the blue litmus paper is immersed into water, the color of the litmus paper will not change. 4. If the red litmus paper is immersed into the orange juice, the color of the litmus paper will not change 5. If the red litmus paper is immersed into the ammonia, the color of the litmus paper will change from red to blue 6. If the red litmus paper is immersed into water, the color of the litmus paper will not change.
