Define ratings of copper corrosion test 1A and 1B?
In standardized test method ASTM D130 for oils or D4048 for grease, the rating of 1A is given for appearance of freshly polished copper coupons, and 1B indicates slight tarnish. The ratings proceed further down the scale as corrosion staining of the test coupon increases, with 4 being the worst (severe corrosion) typically appearing as a blackened test coupon.
Do copper and bleach react with each other?
Yes sodium hypochlorite does react with copper. I did the test where copper was immersed in bleach and the parts near the surface where turning verdigris while the lower ones where getting coroded in a higher rate.
What color does copper nitrate burn in a flame test?
The colour of any sample containing copper ions burns with a bluish green flame in the flame test.
Test for presence of water in anhydrous copper sulphate?
In the presence of water the white anhydrous copper sulfate become blue.
2 Why doesn't fluorine give positive test with Belstein test?
Because in a Belstein test, the copper halide should be able to volatilize to produce green flame, an indication that a halogen is present in the compound. Copper fluoride is not volatile., hence this kind of test is not suitable for the detection of fluorine.

What does copper in your urine mean?
Copper in the urine isn't anything to worry about per say. A 24 hour urine copper test simply measures the amount of copper in the urine. There is a genetic disorder called Wilson's disorder that affects how the body processes copper.
How fast will copper tarnish in fresh water?
Copper exhibits good resistance to corrosion in urban, marine, and industrial atmospheres. The major factors that control the initial rate of attack on copper are moisture, temperature, and the level of pollution. Soon after exposure of copper to the atmosphere copper oxidize, the bright copper surface takes on a dull tan tarnish. After a few years thik tarnish gradually changes to dark brown or black. At a later stage the corrosion products of copper turn green. The corrosion rate of several types of copper in a 20-yr test averaged 1 pm/yr (0.05 mpy) in an industrial atmosphere, 0.8 pm/yr (0.03 mpy) in a marine atmosphere, and 0.5 pm/yr (0.02 mpy) in a rural atmosphere
What is a corrosion experiment name?
This is called a corrosion test, frequently used in quality control of materials.

What should you do if you were changing a valve on a cold water line and discovered a great deal of green copper corrosion where the water that drained out was green?
I would start by getting a water test done to determine what water treatment is necessary.
Test metal for copper?
A magnet does not adhere to copper!
Why is copper reduced to copper IN Benidict test?
Because its a metal
What is chemical testing?
The chemical stress test is used to evaluate the heart.
What has the author A John Sedriks written?

What is copper strip corrosion test ASTM D-130?
ASTM-d130 is a test for evaluation of lubricant additives tendancy to corrode yellow metals. Yellow metal corrosion has become a more critical factor as the EP additives in gear oils have become more concentrated. Older gearboxes with yellow parts (brass, bronze, copper) synchros, and other parts will be damaged by high additive content in some new oils. The ASTM-d130 test rates oils by imersing a prepared copper strip in the lubricant at 2 temperatures in the range typical of the gearbox in service (212 degrees, and 250 degrees F). The ratings go from a "1a" with slight discoloration, but barely noticeable, to a "4c" which is severely corroded, blackened, and pitted. Use care with older gearboxes and highly corrosive oils.
What color does copper nitrate burn in a flame test?
The colour of any sample containing copper ions burns with a bluish green flame in the flame test.
