How would you determine if a sample of gold is pure? a) compare the samples density with that of pure gold b) compare the samples color with that of pure gold c) determine whether the sample is magnetic d) determine whether the sample will fizz in contact with hydrochloric acid

One way of determining if a sample of gold is pure, would be to compare the density with that of real gold.

Gold is a chemical element with symbol Au and atomic number 79, making it one of the higher atomic number elements that occur naturally.

The correct option is A) Compare the samples density with that of pure gold

Comparing and contrasting the density is the best way to determine real gold and fools gold

Hope this helps you
