How can you test strontium nitrate ammonium carbonate and potassium sulfate?
To test for strontium nitrate, you can perform a flame test which will produce a red flame color. For ammonium carbonate, it will release ammonia gas when heated and form a white precipitate when reacted with a sodium hydroxide solution. Potassium sulfate can be identified by its solubility in water, as it is highly soluble.
Why strontium gives crimson colour on flame test?
Strontium gives a crimson color in a flame test due to the excitation of its electrons. When strontium ions are heated, the energy from the flame excites the electrons to higher energy levels. As these electrons return to their ground state, they release energy in the form of light, which for strontium corresponds to a characteristic wavelength in the red part of the spectrum, resulting in a crimson color.
How can you test the precipitate to be sure it contained strontium?
To confirm the presence of strontium in the precipitate, you can perform tests like flame test or use a strontium-specific reagent to observe a characteristic color change or precipitate formation indicative of strontium. Additionally, instrumental techniques like X-ray fluorescence (XRF) or inductively coupled plasma mass spectrometry (ICP-MS) can provide quantitative analysis to confirm the presence of strontium.
Which compound gives a lilac colour in a flame test and makes a cream precipitation when silver nitrate is added?
This compound is potassium chloride.
How can a flame test be used to determine the identity of an element?
Some flame colours are characteristic of metals present, eg Lilac for K+, Red for strontium. However, this is only indicative, because there are a few at least that have a red colour, so it needs to be proven further with a chemical test

What color is the flame test for sliver nitrate?
I presume you mean silver nitrate. A flame test detects only the metal ion in a compound. There isn't one for silver.
What colour flame do you get when you burn strontium chloride?
The flame test for strontium - a strong red color.
What color flame test does selenium nitrate give?
Selenium nitrate typically gives a pink or reddish flame color when subjected to a flame test.
What color does Sr burn in a flame test?
Strontium burns with a bright red color in a flame test.
What happens to lead nitrate in a flame test?
It depends on the conentration, did a test today with several nitrates (incl. lead nitrate) and they were all yellow/orange...
Is there a way to test to see if it is potassium nitrate or ammonium nitrate?
Flame test. Dip a piece of platinum wire into concentrated nitric acid, and then roll it in the sample. Put the wire over a Bunsen flame. If a lilac flame is observed, it is potassium nitrate.
What color flame test does sodium nitrate give?
All sodium salts will give a yellow flame test, because of the metal sodium in the compounds.
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.
Why strontium gives crimson colour on flame test?
Strontium gives a crimson color in a flame test due to the excitation of its electrons. When strontium ions are heated, the energy from the flame excites the electrons to higher energy levels. As these electrons return to their ground state, they release energy in the form of light, which for strontium corresponds to a characteristic wavelength in the red part of the spectrum, resulting in a crimson color.
What element has a ruby- colored flame test?
Strontium usually produces a ruby-colored flame test. When strontium is heated, it emits a bright red flame due to the energy absorbed by the electrons and then released as light in the red part of the spectrum.
What is the color of the flame of barium nitrate?
The flame of barium nitrate typically produces a pale green color when burned. This green color is a characteristic flame test color for barium compounds.
