Colour of ph paper in vinegar

what is a good hypothesis for this lab?? I need to write one.

Acid Base lab INSTRUCTIONS Acid-base indicators are used to let you know whether the solution you are working with is acidic or basic. We have many acid-base indicators available to us today, but the first indicators were made from natural compounds. The indicator that you will be making comes from purple cabbage and is simply called cabbage extract indicator. Procedure: Goggle red cabbage as an acid-base indicator. Go to websites to learn how to make red cabbage pH indicator Make your own pH paper strips using red cabbage indicator with filter paper (or coffee filter). Use the research to design a lab to complete at home. Remember: The procedure should be clear and complete steps that another experimenter could repeat. Test solutions of vinegar, baking soda (dissolve a small amount, 1 tsp, of baking soda into 15mL of water first) and plain water with the pH strips. Test at least 4 other household foods/beverages as non-toxic chemicals to test for pH values. Provide the chemical formula for all 7 of these items. Keep a small amount of the liquid indicator for this step: Slowly add the cabbage extract indicator solution into a small amount of vinegar (approximately 15ml) in a cup just until the colour changes. Repeat this with a solution of baking soda (1 teaspoon in 15 ml of water) until you see a colour change. Mix them together and record what happens. What happens if you mix the vinegar and baking soda solutions together after they have the indicator in them? What solution is this reaction similar to and why? Data: Include (with APA reference) a table of approximate colours of red cabbage indicator solutions at different pH levels and a standard pH table showing colours and numbers to compare your results to. Pictures of your substances and results. A table showing your substances and their pH, based on the colours. State whether each is acid, base or neutral. Discussion questions: What is the significance of “neutral” on the pH scale? What is the colour and pH number of a neutral solution? What happens if you mix the vinegar and baking soda solutions together after they have the indicator in them? What solution is this reaction similar to and why? In the Discussion with reference to your assigned pH values of the seven substances, explain strong and weak acids and bases, and give examples from your lab as references for each. What could you do to neutralize a spill of concentrated acid before cleaning it up to ensure you didn’t get burned? Reference information from the text as well as your observations from the lab (Hint: the mixing of the vinegar and baking soda solutions and noting the colour change)
