What is going on inside atoms of a metal when a metallic salt of that metal is dissolved in water and then placed in a hot flame?
When a metallic salt is dissolved in water, the metal ions present in the salt become hydrated and surrounded by water molecules. When this solution is placed in a hot flame, the water evaporates due to the heat, leaving behind the metal ions. The metal ions then absorb the energy from the flame and get excited, leading to the emission of characteristic colors in the flame test.
What colour flame do you get when you burn copper chloride?
Burning copper chloride produces a green flame due to the presence of copper ions in the compound. The green color is a result of specific energy transitions within the copper ions when they are heated.
What happens if sodium ion is sprayed over the flame?
When sodium ions are sprayed over a flame, they impart a yellow-orange color to the flame due to excitation of the sodium atoms. This phenomenon is used in flame testing to identify the presence of sodium in a sample.
Why does a candle burn with a yellow flame?
Candle burns with a yellow flame because its an incomplete combustion. The temperature of the flame also relates to its colour and also the trace metal ions present will influence the flame colour.
What is a hypothesis for a flame test?
A hypothesis for a flame test could be that different metal ions will produce unique and identifiable colors when heated in a flame due to the characteristic energy levels of the electrons in each metal ion.
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 do you use a metal-nitrate in a flame test?
Metal nitrates are used in flame tests because they are easily converted into metal ions when heated in a flame. The metal ions then emit characteristic colors of light, allowing for the identification of the metal present based on the color produced.
What ions gives a bright orange flame test?
The presence of sodium ions typically gives a bright orange flame test. Sodium compounds such as sodium chloride or sodium carbonate produce this distinctive color when heated in a flame.

Does sodium give off an orange flame?
sodium gives off an orange to yellow flame colour
What ion gives a bright yellow-orange flame test?
Sodium ions give a bright yellow flame color during a flame test.
When you cook spaghetti in water you have salted with NaCl When the water boils it causes the flame of the gas burner to turn bright orange How would you explain the appearance of a color in the flame?
The bright orange color of the flame is due to the presence of sodium ions from the salt (NaCl) in the water. When heated, the sodium ions get enough energy to become excited and emit light in the form of an orange color. This phenomenon is known as flame coloration.
What part of the salt is responsible for the flame color?
The metal ions in the salt are responsible for the flame color. When the salt is heated, the electrons in the metal ions absorb energy and jump to higher energy levels. As they return to their original state, they release energy in the form of light, which gives the flame its color.
What happens if sodium ion is sprayed over the flame?
When sodium ions are sprayed over a flame, they impart a yellow-orange color to the flame due to excitation of the sodium atoms. This phenomenon is used in flame testing to identify the presence of sodium in a sample.
Why do chlorides burn different colors?
Chlorides burn different colors because the flame color produced is dependent on the specific metal cation present in the compound. Each metal cation emits a unique spectrum of colors when heated in a flame due to the excitation of electrons to higher energy levels and subsequent emission of light as the electrons return to their ground state. This property is utilized in flame tests to identify the presence of specific metal ions in a substance.
What colour flame is sodium bromide?
Sodium ions (Na+, from any sorium salt) produce an yellowish orange colored flame with wavelength averaging at a 589.3 nm (actually two dominant spectral lines very close together at 589.0 and 589.6 nm).
