PHYSICAL SCIENCE REPORT – ACIDITY OF DOMESTIC SUBSTANCES1. INTRODUCTION I think the experiment was interesting to see how chemicals, including common household products, can be acidic, basic or neutral. It was very interesting to learn that many acids are not dangerous. Some are also found in the food we eat. Any food that tastes sour is sour. The bases are also found in common household products. They can be very strong and dangerous or weak and safer for home use.2. Investigative QUESTIONTo demonstrate how many levels of acidity there are in our household products and foodsNEUTRAL ACID BASECoffee Ammonia Olive oilLemon juice Baking soda Melted butterSoda Pop Cough medicine Vegetable oilOrange juice Liquid soaps Promise (contains neutralizer)Detergents for vinegar drains Milk (skimmed white)3. HYPOTHESISBased on the experiment with red cabbage, I can tell whether a liquid is acidic, basic or neutral using red cabbage juice as an indicator.• If the liquid turns red then it is an acid• If it turns green then it is a base• If the liquid remains purple then it is neutral4.
