Universal indicator and pH by Christopher Acosta https://padlet.com/christopheracosta211/s0vgrtu5eu5j2tsn A view on how universal indicator can be made at home and testing households fluids to see what color they change to depending on their pH. en-us 2021-06-12 19:20:35 UTC 2024-10-01 05:03:41 UTC hello@padlet.com Hypothesis christopheracosta211 https://padlet.com/christopheracosta211/s0vgrtu5eu5j2tsn/wish/1602764536 The more acidic the pH of the liquid I test is, the redder the color will be and the more basic the pH of the liquid will be, the more blue the color will turn. Prediction: bleach will be greenish-blue and lime will be orangish.

    Step 2: Add your cabbage and some water to a bender and blend for 3-5 mins.
    Step 3: Strain the cabbage indicator to get rid of the foam and cabbage residue.
    Step 4: Pour your cabbage indicator into separate cups equally
    Step 5: Pour in some drops of each liquid into each of the separate cups to test until you see a bit of color change.
    Step 6: Stir each cup with different spoons until you see the color change
    Step 7: Record your results 
    Step 8: Repeat the experiment or parts of it if something is inconsistent or doesn't make sense.

In my experiment, I was able to find out the pH of the same liquid doesn’t really change much. So the pH of a lime someone has is very similar to the pH of a lime that I have. Though, probably the biggest findings was the fact that there are some liquids that will change color  depending on how much you put in and some that don’t. For example, if I put in small amounts of bleach, it would turn the indicator dark blue. Too much of it though and it would turn the color yellow. Though, this doesn't consist of every liquid as when I tested the water, I poured it up to the brim and it didn’t change, so it depends on the liquid. The data supports my hypothesis and the claim of acid liquids being more red while alkaline liquids being more blue. Bleach did turn dark blue before I poured too much and got yellow. From what I researched, acids turn redder and therefore have a low pH because they have a higher concentration of Hydrogen than water while alkaline solutions have a low concentration of Hydrogen lower than water making it blue and dark purple. Thus, the conclusion I got from my experiment does match up from what I learned and allowed me to easily detect which solutions are acidic, alkaline or basic. When looking at the limitations of my experiment, not having a completely clean cups or having some water in the cups before pouring the indicator, not using the purest of liquids tested (maybe the bleach I tested isn't 100% bleach), and having to used tap water instead of distilled water for my cabbage indicator might alter my results. If I could analyze more data, I would definitely have stronger acids and bases. This data I found inspires me to test how the pH of a liquid affects the taste of the liquid? Also, how mixing liquids with different pH’s changes the pH of the liquid? Lastly, does the amount of a liquid you test change the pH or color?
