Why is it important to use a clean nichrome wire for each flame test?
The wire simply holds the sample in the flame. Nichrome wire has such a high melting point that the relatively low temperature of the burning flame won't drive any of the Ni or Cr atoms into the ionic state and interfere with the color of the ions in the compound which is adhering to the wire.
How do you use NiChrome wire?
One use for NiChrome wire is to make electrical heating elements.
How do you test the copper two ions?
A Flame Test. Using a platinum or nichrome wire. Clean the wire in hydrochloric acid, Then dip the wire into a solution containing copper(II) ions. e.g. copper sulphate solution. The pass the wire through a Bunsen burner flame. The flame should burn a green/blue colour.
What has more resistance a nichrome wire or a copper wire?
Nichrome wire has such high resistance that it is used to convert electrical energy into heat. Many heating elements are made from nichrome. Copper wire has the best conductivity, for the price, of any metal.
What is the solute and solvent of the nichrome wire?
Nickle

What happens to a nichrome wire when someone turns on a switch?
It will get heated and start to glow.
Why is it necessary to clean the platinum wire between flame tests?
because platinum wire loops dont impart any color of it own.... NICHROME wire are also used..

What element is used in electroplating and nichrome wire?
nickel!
Should the heating element of an electric iron be made of of iron Silver or nichrome wire?
It should be made of nichrome wire because resistivity of nichrome is high.Its high resistivity causes nichrome to heat up faster, when an electrical current is passed electricity moves through the wires, givingheat to the element.hope it helped
How is toast made?
Toasters use Nichrome Wire that is wrapped around a Mica Sheet. Nichrome Wire produces infared radiation. This produces the heat that "toasts" the bread. You can usually see this yourself! When the coils inside the toaster start to become red, that means the Nichrome wire is starting to produce infared Radiation.A timer is set to stop the Nichrome Wire from producing heat, and a spring-loaded tray pops the toast out of its slot.
What happens to the matter in copper wire when heated?
The matter in copper wire melts then explodes into a green flame
What wire is used for an immersion heater?
An immersion electric heater usually uses nichrome wire as the heating element. Nichrome is highly resistive, and by applying a voltage, we can get it pretty hot. Nichrome is used as the heating element in toasters and on electric range elements as well as lots of other places.
