Data: I Solution Result I Basic Softener Bleach I Acid I Base Acid IN/A Dishwashing Liquid Dishwashing Detergent I Laundry Detergent Laundry Stain Remover I ‘Fabric Mayonnaise/Miracle Whip I Baking Powder I White Vinegar I Cider Vinegar I Lemon Juice Soft Drinks I Mineral Water I Milk Conclusion: upon testing these household objects I discovered some things that already knew; vinegar is extremely acidic, while baking powder is a base, and some things that didn’t know; milk is acidic and laundry detergent is a base.
Any solution that has an WA as a result either could not find or did not own. Had the most trouble with bleach because at first, when added the cabbage juice, it didn’t change color. I emptied the beaker because it had a bit of baking powder in it, and then upon my second try it still didn’t do anything. Had to add a large amount of the juice to the bleach before it actually began to change color.
