List the apparatus and the method for determining if the solutions are acidic or basic. Also list the hypothesis for the investigation.

Here is a possible method for the investigation based on the provided apparatus and the aim of determining the pH of household substances:

METHOD

1. Preparation of Samples:

   • Label 12 clean test tubes for each of the following substances: Distilled water, Saltwater solution, White vinegar, Lemon juice, Handy Andy solution, and Baking soda solution.
   • Pour approximately 5 mL of each substance into its respective labeled test tube. Ensure the saltwater, Handy Andy, and baking soda solutions are prepared by dissolving 1 tablespoon in 50 mL of distilled water as indicated.

2. Preparation of Red Cabbage Indicator:

   • (If not already prepared) Use the blender to blend red cabbage with some distilled water. Strain the mixture to obtain red cabbage water.

3. Testing with Universal Indicator:

   • Place a small amount (e.g., 1-2 mL) of each household substance into separate wells of a cavity tile or onto a white saucer.
   • Using a medicine dropper, add 2-3 drops of universal indicator solution to each substance.
   • Observe and record the color change for each substance.
   • Compare the observed colors to the pH chart to determine the approximate pH value and classify each substance as acidic, neutral, or basic.

4. Testing with Red Cabbage Water Indicator:

   • Clean the cavity tile/white saucer thoroughly with distilled water from the wash bottle.
   • Repeat Step 3, but this time add 2-3 drops of red cabbage water indicator to each substance.
   • Observe and record the color change for each substance.
   • Note whether the color change indicates an acidic, neutral, or basic nature.

5. Data Recording:

   • Create a table to record the initial color of each substance, the color after adding universal indicator, the corresponding pH from the chart, the color after adding red cabbage water, and the final classification (acidic, neutral, or basic).
