Bleach and Stain Type

  Dependent Variable: The dependent variable in this study is the effectiveness of stain removal, measured by the extent to which stains (Coffee, ketchup and soy sauce) are eliminated from fabric or surfaces. Independent Variable The independent variable is the type of stain remover used. It includes various substances such as distilled white vinegar, baking soda, lemons, hydrogen peroxide, oxygen-based bleach, borax, talc, and cornstarch. Controlled Variables To ensure the validity of the experiment, certain factors must be controlled. These include the type and amount of fabric or surface material, the duration of stain exposure, the concentration of stains, and the environmental conditions (temperature and humidity) during the experiments. Hypothesis If we use different stain removers, then some of them will be better at getting rid of stains..

Big Question      How does the nature of stains (coffee, ketchup, or soy sauce) influence the effectiveness of bleach and homemade stain removers, and what chemical reactions are involved in the stain removal process? KEY WORDS Chlorine : a halogen element that is isolated as a heavy greenish yellow gas of pungent odor and is used especially as a bleach, oxidizing agent, and disinfectant in water purification. Vinegar :a sour-tasting liquid containing acetic acid, obtained by fermenting dilute alcoholic liquids, typically wine, cider, or beer, and used as a condiment or for pickling. Whitening :The active ingredient in most whitening products is hydrogen peroxide (H2O2) which is delivered as hydrogen peroxide or carbamide peroxide. Discolorize : cause to lose or change color. Disinfectant : a chemical liquid that destroys bacteria. Clorox :  blanching agent, bleach, bleaching agent, whitener. an agent that makes things white ...

 Wednesday, November 1st, 2023 Today we got together and established the Big question and Background questions. Thursday, November 2nd, 2023 Today we learn how to use "Blogger" and show our logbook digitally. Tuesday, November 7th, 2023 Today we learned how to find the background research using chatgpt. We analyzed it and enhance it more. We also updated our Science fair journal draft in "Google Docs". Wednesday, November 8th, 2023 Today, we redid our background research and updated the information in our blog. Thursday, November 9th, 2023 Today we finish the first part of our logbook. We established the variables and hypothesis. we updated our blog. Tuesday, January 9th, 2024 Today we designed our project and also changed the hypothesis. Wednesday, January 10th, 2024 Today we wrote the design of our project. We research how to made a homemade stain removal. Tuesday, February 20th, 2024 Today we are making our color scale chart, and updating our blogg. Monday, March...
