Answer:
So...yeah
Step-by-step explanation:
the chemical substance and apparatus needed to investigate the nature of pH of a sample of onion solution?
To investigate the pH of a sample of onion solution, you will need:
1. Red and blue litmus paper
2. pH paper or pH meter
3. Onion solution (prepared by grinding or blending onions and mixing with distilled water)
4. Beaker or test tube
5. Stirring rod
To perform the experiment:
1. Pour the onion solution into a beaker or test tube.
2. Dip a piece of red litmus paper into the solution. If it turns blue, the solution is basic. If it remains red, the solution is acidic.
3. Dip a piece of blue litmus paper into the solution. If it turns red, the solution is acidic. If it remains blue, the solution is basic.
4. Alternatively, use pH paper or pH meter to determine the exact pH of the onion solution.
5. Record the results and observations.
