Question

Gold used in making jewellery is a :

• A. homogenous mixture
• B. heterogenous mixture
• C. pure substance
• D. All of the above

Answer 1

heterogenous mixture

Pure gold is too soft to be used and, so it is mixed with other metals such as silver, copper, nickel to make it harder. Thus gold used in jewelry forms a uniform mixture with other metals. Hence option B is correct.
