What are other ways to detect metal ions in a compound other than doing flame tests?
For Carbonates- dilute HCl on the surface of the substance then bubble gas through lime water
For Sulfates- Add Dilute HCl and then Barium chloride solution. A white Barium sulfate precipitate means the original compound was a sulfate
Halides- Add dilute Nitric acid followed by silver nitrate solution.
Cl- white precipitate
Br- Cream precipitate
I-yellow precipitate.
For nitrates- add aluminium powder+ sodium hydroxide and heat. If damp red litmus paper turns blue ammonia is present.
You can also add certain substances to water, then add dilute NaOH to make certain coloured precipitates.
Cu2+-Blue
Fe2+-green
Fe3+- Brown
Mg2+-white
Ca2+-white
Al3+-white

Which combination describes the flame color of the compound when heated?
Which combination describes the flame color of the compound when heated?
Is the flame colour a test for the metal or for the nitrate in each compound?
The flame color test is typically used to identify the metal present in a compound. When the compound is heated, the metal ions absorb energy and release it as light in different colors, which can help identify the metal present. Nitrate ions do not typically contribute to the flame color observed.
Why are the metals in a flame lab test used in a chloride compound instead of just by themselves?
Metals are used in a chloride compound in a flame test because the chloride compound helps to enhance the visibility of the colored flame. When the compound is heated in a flame, the metal ions in the compound absorb energy from the heat and emit light in specific colors, making it easier to identify the metal present.
Can a flame test be used to identify a non metal atom in a compound?
No, a flame test is typically used to identify the presence of certain metal atoms in a compound based on the characteristic colors they emit when heated. Non-metal atoms do not typically produce colored flames, so a flame test is not suitable for identifying non-metals in a compound.
What is the flame test color of distilled water?
Distilled water does not produce a flame test color because it does not contain any significant amount of metal ions that are responsible for producing colored flames. The flame test is typically used to detect the presence of metal ions in a sample.

When the compound is heated in a flame, the metal ions in the compound absorb energy from the heat and emit light in specific colors, making it easier to identify the metal present.
What can a flame test tell you about a certain compound?
No, because non metal atoms do not enter an excited state.
Can a flame test be used to identify a non metal atom in a compound?
No, a flame test is typically used to identify the presence of certain metal atoms in a compound based on the characteristic colors they emit when heated. Non-metal atoms do not typically produce colored flames, so a flame test is not suitable for identifying non-metals in a compound.
When doing flame tests Li Cl and K Cl both contain Cl so what makes the flame tests different colors?
The flame tests are different because they contain different metal cations. Since the metals were the variable that you changed, you know that can be the only reason why the flames would be different colors.
What is the flame test color of distilled water?
Distilled water does not produce a flame test color because it does not contain any significant amount of metal ions that are responsible for producing colored flames. The flame test is typically used to detect the presence of metal ions in a sample.
What happens to a metal atom when a splint soaked with chloride and placed in a flame and color is produced?
When a metal atom is heated in a flame with a chloride compound, the metal atom absorbs energy and is excited to a higher energy state. As the metal atom returns to its ground state, it emits light of a specific wavelength, resulting in the production of a characteristic color. This color can be used to identify the metal present in the compound.
What color is sucrose in a flame test?
Sucrose does not produce a flame test color as it is a compound made up of carbon, hydrogen, and oxygen. It does not contain metal ions that are responsible for producing flame colors.
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.
Would you characterize a flame test sensitive?
Yes, a flame test is considered sensitive because it can detect the presence of various metal ions in a sample based on the color of the flame produced when the sample is heated. Different metal ions produce characteristic colors when placed in a flame, allowing for their identification even in trace amounts.
What flame color does aluminum nitrate produce?
Aluminum nitrate does not produce a specific flame color when burned. The flame color produced by a compound is typically due to the metal ion present, rather than the nitrate anion. Aluminum itself does not produce a significant color in flames.
