Question

Give scientific reason for the following :
Ornamental gold is an example for homogeneous mixture.

Answer 1

Several metals can be melted together with gold forming different alloys. These are in fact, at room temperature, solid solutions thus homogenous mixture

This is done either to change the color of the gold, or to harden it, making it more durable and suitable for ornaments. It also becomes less expensive. The usual term indicating the purity of gold is ‘karat’. Pure gold is 24-karat. Other usual concentrations are 75% gold - 18 karat, 58.3% gold - 14 karat and 41.7% gold - 10karat

Answer 2

Dear Student,

◆ Ornamental gold is an example for homogeneous mixture because -

• Gold is a noble metal, hence used for jewellary.
• But 100% gold is too soft & weak and breaks very easily.
• Thus, gold is mixed with copper/silver in uniform mixture to make jewellery.
• As this mixture is uniform, ornamenatal gold is called homogenous mixture.

Thanks dear. Hope this helps you..
