To make sure any substance or gas released does not travel to someone's face directly. (safety)
tilting the tube increases surface area of the solution inside, gas reaches the surface easier and at a shorter distance. the solution is exposed to more air. if adding anything, more of the substance reacts at once with higher surface area and less depth.

How can you test strontium nitrate ammonium carbonate and potassium sulfate?
A flame test.
Is the flame test a qualitative or quantitative test for the identity of an unknown?
just looking at the color of the flame --- qualitative
What is the result with iron II chloride in the test flame?
Iron has a yellow-gold color in the flame test.
Which metal reacts with water and burns with a lilac flame?
Potassium has a violet color in the flame test.
What color does sodium hydroxide burn in a flame test?
Bright yellow :: This is the sodium ions. Any sodium compound will give a flame test colour of yellow/
Why was the test tube held in the flame at a 45 degree angle?
At this angle the biggest "area" of the test tube is covered by the flame. Thus it heats up quickly and evenly. Also, by holding the test tube at 45 degrees away from you, you're less likely to be splashed by anything in the test tube boiling over.
Is a flame test a qualitative or quantitative test?
The flame test in analytical chemistry is only qualitative.
How can you test strontium nitrate ammonium carbonate and potassium sulfate?
A flame test.
What is the color of iron in aflame?
If you're referring to what chemists call a "flame test", then the characteristic color due to iron ions is yellow (which may not be terribly spectacular, depending on how hot the flame in question is). If you're referring to the color of an iron bar held in a flame, it depends on how hot the flame is; if it's held there long enough, it should be approximately the same color the flame itself is (assuming it doesn't melt first).
What color does Na-Cl burn in a flame test?
NaCl burns yellow in a flame test.
What is the flame test for aluminum?
Aluminium ions like Magnesium ions have no colour in a flame test
How do you know if something is copper for example a vase?
you need to do the flame test you need to do the flame test
How do you test for potassium ions?
Flame test
Does Copper Chloride produce a blue-green or Red flame?
In a flame test the copper ions in copper chloride will produce a 'blue/green' flame. To test for metal ions, the flame colour in a flame test is indicative of the metal present. Lithium = Red Sodium = Yellow Potassium = Lilac (pale purple). There are many more flame test colours.
Examples of constant variables in flame test?
The temperature of the flame.
What was the flame test original use?
The flame test is used for the qualitative determination of some ions in solution.
What is the result with iron II chloride in the test flame?
Iron has a yellow-gold color in the flame test.
