How do you find silver?
Silver is typically found in nature as a byproduct of mining for other metals like lead, zinc, or copper. It can also be found in its pure form in certain deposits and ores. Geologists use various exploration techniques such as surveys, drilling, and sampling to locate silver deposits underground or in surface outcrops.
How do you test a metal to determine if it is silver and how do test silver quality?
To test if a metal is silver, you can perform a magnet test (silver is not magnetic), a nitric acid test (silver does not react with nitric acid), or a specific gravity test (silver has a unique density). To test the quality of silver, you can check for hallmarks or stamps indicating purity, conduct an acid test to determine silver content, or use an electronic tester for a quick assessment.
Which test or observation can be used to show that a sample of glucose is pure?

How can you know a colorless water is pure?
