Question

Few questions, help?

Answer 1

1.What was the color of the indicator at acidic, neutral, and basic conditions?


2.What chemical changes were responsible for the color changes?


3.Label the materials you tested as acidic, basic, or neutral.

4.Which group contains items used for cleaning or personal hygiene?

Answer 2

this sounds like a mini-lab of sorts and your questions are unanswerable if I (or others) did not perform this or observe this, nor have you provided us with all of the information.

Answer 3

Red for acidic and blue for alkaline lol

Answer 4

this seems like an incomplete question.

Answer 5

Do you guys want me to post the lab and would you guys take educated guesses? It's about red cabbage @mastermindkakashi @sarahshamim @nopen I don't have any red cabbage so I have no idea how I'm going to do this.I should probably try with green if I don't get anything in a few.

Answer 6

that would be helpful :)

Answer 7

Put ½ cup of finely chopped red cabbage leaves in a jar and add ½cup of hot water. Stir and crush the leaves with a spoon. Continue the extraction process until the water is distinctly colored.
Strain the extract through a piece of cloth into a clean jar. This liquid is your natural indicator.
Tape three sheets of paper end to end. Draw a line along the center and label it at five cm intervals with the numbers 1–14. This is your pH scale.
Pour your indicator into each of three plastic cups to a depth of one cm. Add several drops of vinegar to the first cup, add a pinch of baking soda to the second cup, and add several drops of ammonia to the third cup. The resulting colors indicate pH values of about 3, 9, and 11, respectively. Place these colored cups in the correct positions on your pH scale.
Repeat Step 4 for household items such as table salt, borax, milk, lemon juice, laundry detergent, dish detergent, milk of magnesia, toothpaste, shampoo, or carbonated beverages. Test a minimum of five household items using your natural pH scale.
good timing I just checked.

Answer 8

well I can tell you that any soaps or detergents and milk you use are bases. carbonated beverages and lemon juice are acidic.

Answer 9

Thanks, I appreciate that help. ^_^ Also do you understand number 4? I need a bit of clarification.

Answer 10

it's like, are the chemicals or substances that you use to clean (like soap or bleach) acids, bases, or neutral?

Answer 11

I'm think it's bases

Answer 12

number 4 is just asking what you would use to take care of yourself, like soap and shampoo or hair gel, etc. I mean, you wouldn't use milk to clean yourself right?
