Quiz Answer Key and Fun Facts

1. Gold is a very inert metal so it does not react with most chemical substances. Aqua regia is one of the very few substances that can dissolve gold. Which two acids make up this solution?

Answer: Hydrochloric acid and nitric acid

In Latin, aqua regia means royal water. It can also dissolve platinum.

2. Pure gold is non-toxic.

Answer: True

You may have heard of metal leaves that are used to decorate food. In fact, gold is an approved additive substance in the European Union.

3. Due to its great physical resemblance to gold, pyrite is also known as the fool's gold. Which two elements make up pyrite?

Answer: Iron and sulfur

The chemical formula of pyrite is FeS2. It is used widely in the production of sulfur dioxide.

4. The Latin name for silver is argentum. Is it true that argentum is mixed with mercury to produce amalgams that are used in dental fillings?

Answer: Yes

In fact, there are many other substances that can be mixed with mercury to produce amalgams, such as tin, copper and zinc.

5. Both gold and silver belong to which classification group in the periodic table of chemical elements?

Answer: Transition elements

Gold (aurum) has an atomic number of 79 while silver (argentum) has an atomic number of 47. They are both in group 11 in the periodic table of chemical elements. While silver is in period 5, gold is in period 6.

6. Two silver compounds play an important role in the photography industry. One of them is silver halide. What is the other one?

Answer: Silver nitrate

Silver nitrate (AgNO3) is extremely photosensitive. It is also used as an antiseptic.

7. Aluminum bronze is known for which special property?

Answer: High corrosion resistance

When aluminum bronze reacts with oxygen molecules from the atmosphere, aluminum will react with oxygen first to produce aluminum oxide (alumina). This forms a protective layer to prevent further corrosion of the aluminum bronze alloy.

Answer: It combines with chloride ions to form silver chloride precipitate.

All nitrate ions compounds are soluble in water. Since aqua regia is a mixture of concentrated hydrochloric acid and nitric acid, chloride ions and nitrate ions present in the solution. Chloride ions will combine with silver to form silver chloride precipitate. Further treatment will be carried out to recover silver from the precipitate.

Now, gold and other metals will all dissolve in aqua regia. By using specific (only selective towards gold) reducing agents, pure gold powder will be separated from other metals. To get the gold we are interested in, a series of washing and drying process will be carried out to obtain the pure gold grain we are interested in.

9. Electrum is a naturally occurring alloy that is made up of ___.

Answer: Gold and silver

Sometimes, a trace amount of copper and other metals is also present in electrum. Electrum was used in ancient times to make drinking vessels and coins.

10. Are gold, silver and bronze all elements?

Answer: No

Gold and silver are elements, but bronze is a type of copper alloy. Tin is one of the main components in bronze, others being phosphorus, aluminum, manganese and silicon.
