To write a prediction on a flame test, you need to state the color of the flame that you expect the sample to produce based on the known properties of the element present in the sample. For example, if you know that the sample contains sodium, you could predict that it will produce a bright yellow flame. Make sure to explain the reasoning behind your prediction using the spectral properties of the element.
The flame test for nickel produces a blue-green color flame.
Cobalt gives a blue flame test while chromium gives a green flame test.
need to find the answer to what doe slithium carbonate look like in a flame test
Calcium typically produces an orange-red flame when subjected to a flame test.
A yellow flame in a flame test usually indicates the presence of sodium in the sample being tested. Sodium typically produces a bright yellow flame when heated.
The independent (or explanatory) variable is changed to test the prediction,

hypothesis :)
The flame test in analytical chemistry is only qualitative.
That is a hypothesis.
Cesium burns with a lilac or bluish-violet flame in a flame test.
The flame test for nickel produces a blue-green color flame.
Cobalt gives a blue flame test while chromium gives a green flame test.
Chlorine gas itself does not emit a colored flame when subjected to a flame test. Instead, it will impart a green color to the flame when a sample containing chlorine (such as a chloride compound) is included in the flame test.
It is not the anions (e.g. iodide) that are responsible for the flame test color, rather the cations such as sodium ion, potassium ion and calcium ion give you different colors.
That is a hypothesis.
The colour turns brick Red .
