Nomenclature and Household Items

Transcription

1 Nomenclature and Household Items NAME: DATE: PERIOD: Background: Many household items contain chemicals that are commonly used in everyday life. Some chemicals are edible while other compounds would be poisonous to consume. Many non-edible household chemicals are used as cleaners. Soaps, detergents, drain-openers, countertop sprays, oven sprays, furniture polish, air fresheners and floor cleaners are examples of chemical s that are commonly used inside the home. Other chemicals are edible and can be used for cooking or in medication. Baking soda, sugar, salt and baking powder are all edible s commonly used in cooking. Antacids, aspirin and vitamin C are edible s that are used as medicines. Household items can be classified as acids (ph<7), bases (ph>7) or neutral (ph=7). Soaps, detergents, drain-openers, antacids and ammonia can be classified as bases. Antacids contain carbonates, bicarbonates and hydroxides to neutralize the hydrochloric acid in the stomach. Aspirin (acetyl salicylic acid), Vitamin C (ascorbic acid) and vinegar (solution of acetic acid) can be classified as acidic. Product containers list valuable information such as ingredients, warnings, customer service numbers and expiration dates. The chemical name listed first on the ingredient list is the component of that. The warning label will vary with the chemical hazard of the ingredient. In this lab many household items will be viewed to obtain the chemical name. The chemical name will then be used to write the formula of the compound. Procedure: 1) Visit each lab station and copy down the name of the. 2) Decide the use for the (cooking, cleaning, medicine) and write in the usage column. 3) Look on the ingredient list to find the component of the. Write the name of the the appropriate column. 4) Looking at the name of the component, write the formula of the. 5) Look to see if the has a warning or hazard listed. Write Yes if the has a hazard or warning. Write No if the does not list a hazard or warning.

2 Data: Substance Substance Usage Name of Formula of Hazard or Warning Conclusion: True or False 1) Warning labels occur ly on s that are used for cooking. 2) NaCl and NaHCO 3 are edible compounds used in cooking. 3) Sodium hypochlorite is used for soaking sore feet. 4) Magnesium sulfate heptahydrate is used to bleach material. 5) The compound listed first on the ingredient list is the that. 6) The shampoo is water. 7) Household s can be classified as acidic, basic or neutral. 8) Ammonia, antacids and aspirin are acidic compounds. 9) Antacids can contain OH -1, CO 3-2, HCO 3-1 ions. 10) Table salt and baking soda both contain a sodium ion.

3 Teacher Notes: Nomenclature and Household Items Set-up: Obtain 12 note cards and write numbers # Evenly space cards around the lab tables. Tape the cards to the table. Take the twelve items and write numbers #1-12 on each with a permanent marker. Place the item by the appropriate card. Items: Items will vary by brand names. When looking for items to purchase, look on the back of the product label to make a match to the ingredient. This activity can be stored from year to year in a box since the containers are never opened. The purpose of this activity is not only to transfer names to formulas but also to allow students to see household items in the lab and to make the association that everything is made up of chemicals.
