Quiz Answer Key and Fun Facts

1. What is the active ingredient in laundry bleach?

Answer: Sodium Hypochlorite

A solution of 3 to 6 percent of sodium hypochlorite in water is commonly called bleach.

2. Laundry bleach, or its active ingredient, is used in a number of applications. Name the odd one out.

Answer: Food Additive

Although food processing equipment is often cleaned with sodium hypochlorite solution, it should be washed off thoroughly. By US governmental regulation, only concentrations lower than 0,02% are tolerated within the wash water.

3. What type of chemical agent is bleach's active ingredient?

Answer: Strong oxidizer

Oxidizers can readily transfer oxygen atoms or gain electrons in a redox reaction.

4. For all kinds of reasons, people like to bleach their hair. What kind of bleaching agent is often used?

Answer: Hydrogen peroxide

For the sake of clarity, dihydrogenoxide is merely water. You definitely do not want to use hydrochloric acid, or you'll end up with a red scalp.

Answer: Chloramines

Amines from urine react with chlorine left from the bleaching agent and form so called chloramines. Monochloramine, dichloramine, and nitrogen trichloride are the substances that cause eye and respiratory irritation.

6. Might bleach interfere in forensic luminol testing for blood?

Answer: Yes, it could, but its effect will deteriorate over time making testing possible.

Bleach is often used by criminals to cover up their crime. Luminol testing is the choice of forensic investigators for establishing blood contamination in a crime scene. Bleach does interfere with this testing, as luminol is sensitive to oxidizing agents and would render the investigation inconclusive.

However, hypochlorites are unstable and deteriorate over time, making the latent blood testing possible, without interference of hypochlorites.

7. Another type of bleach other than common household bleach has made its entry in the commercial marketplace over the past years. What is it commonly called?

Answer: Oxygen bleach

Oxygen bleaches contain hydrogen peroxide or compounds which release peroxide.

8. What is the name of the bleaching agent in commercially available tooth whitening products?

Answer: Carbamide peroxide

Carbamide peroxide is an oxidizing agent, also called urea peroxide, urea hydrogen peroxide and percarbamide. It is an adduct of urea and hydrogen peroxide.

9. Which of the below compounds is a compound once found in many skin whitening products but which was banned from use by the European Union due to its suspected carcinogenic properties?

Answer: Hydroquinone

Hydroquinone has been banned from use in cosmetic products by the European Union, Australia and Japan. However, it can still be purchased in the US.

10. Where should you store your dangerous household products such as bleach?

Answer: In a closed cupboard, out of reach from children

Children are curious human beings and you should avoid their contact with dangerous goods any time.
