How do you identify zinc?

Answer 1

Using Electrolosis remove the copper coating from a penny made after 1982 by connecting it to the anode for a while. Then clean the penny and place it in a high humidity area of your house with a small amount of water. The green stuff that grows on it will be sulfate of zinc.

Answer 2

You can test very simply, even at home. All you need is some copper wire, a volt meter, some water, and a bit of table salt. Mix about a teaspoon of salt into a glass of water. Strip the insulation from a short length of copper wire. Attached the positive meter lead to the copper wire and the negative to the metal sample you want to test. Partially immerse the wire and metal sample (not touching each other) in the salt water, being careful to keep the meter leads out of the water. If the entire immersed area of your sample is reasonably pure zinc, the meter should read around 0.9 volts. For more information, research "galvanic cell".

Answer 3

1, the density of zinc and aluminum a lot of difference, some difference over two zincaluminum light weight.

2 fresh look color zinc and aluminum are similar, significant differences from time to time the color will be: zinc darken significantly, almost no discoloration of aluminum.

Three voices: the voice of dull zinc, aluminum and more crisp sound.

Answer 4

You don't make zinc -- you find it. It is a naturally occurring element. It cannot be made, only isolated from other things.

Answer 5

used mainly in the ship/boat industry , there are tiny amounts of it in our bodyy tooo.

Answer 6

density of a metal sample is 7.0 g/ml. what two ways can I determine if it is tin or zinc?

Answer 7

To obtain zinc is to reduce the calamine on it with a thick, strong block of charcoal.

Answer 8

The standard method is to put a sample of the zinc into a mass spectrometer. This will give a different peak for each isotope present.

Answer 9

Still no answer whats the
