When an alkali metal salt drawn into a non-luminous flame will ionise, absorb energy from the flame and then emit light of a characteristic wavelength as the excited atoms decay to the unexcited ground state.
So,the intensity of emission is proportional to the concentration of the element in the solution.
A photocell detects the emitted light and converts it to a voltage, which can be
recorded.
By this we can estimate the conc of Na.
What else can I help you with?
How do you check the presence of sodium in different in different compounds?
One common way to check for the presence of sodium in compounds is by using a flame test. When the compound is heated in a flame, sodium will produce a characteristic bright yellow color. Alternatively, sodium compounds can also be detected by performing chemical tests, such as using silver nitrate to precipitate sodium chloride.
Which elements may be excited using a Bunsen burner flame?
Metals such as sodium, potassium, calcium, and copper can be excited using a Bunsen burner flame to emit characteristic colors. This technique is commonly used in flame tests to identify different elements based on the color of light they emit when heated.
What color does sodium nitrate burn?
In a flame test , the sodium ion will produce a bright yellow flame. The nitrate ion does not produce a colour. Dissolve sodium nitrate in water. Then using a ni-chrome wire, clean it in hydrochloric acid, dip the clean wire intoi the solution. Then pass the wire through a bunsen flame. The pale blue flame, will become bright yellow. Different metal ions produce different flame colours. Lithium = red Potassium = lilac Copper = Blue/green
Chemical test can distinguish sodium carbonate form potassium hydroxide?
- use a flame test to distinguish between sodium and potassium - use flame photometry to determine sodium and potassium - heat sodium carbonate and collect the gas in a beaker with water: the gas released is carbon dioxide; see the bubbles. Measure the pH; it will be more than 7.
What color flame would potassium ions make using sodium and potassium ions?
Potassium ions typically produce a lilac or light pink flame color when burned. When mixed with sodium ions, the flame color might have a slightly different hue due to the presence of both elements, but it would still be in the violet range of the color spectrum.
Can you determine lithium and calcium using photoelectric flame photometer?
Yes, it is possible.
What color flame does potassium ions produce in a flame emission photometer?
Potassium ions produce a lilac or light pink flame when using a flame emission photometer. The color is distinct and helps to identify the presence of potassium in a sample based on the emission spectrum produced when the sample is exposed to heat in the flame.

Alternatively, sodium compounds can also be detected by performing chemical tests, such as using silver nitrate to precipitate sodium chloride.
Why is it difficult to identify potassium ions and sodium ions in low sodium salt using a flame test?
When sodium is subjected to a flame test, it burns a bright yellow. This yellow flame can be brighter than the lilac flame color of the potassium, which makes it more difficult to distinguish between the sodium and potassium.
Which elements may be excited using a Bunsen burner flame?
Metals such as sodium, potassium, calcium, and copper can be excited using a Bunsen burner flame to emit characteristic colors. This technique is commonly used in flame tests to identify different elements based on the color of light they emit when heated.
Sentence using affinity?
Sodium, when exposed to air has a great affinity for oxygen, such that it bursts into flame
What color does sodium nitrate burn?
In a flame test , the sodium ion will produce a bright yellow flame. The nitrate ion does not produce a colour. Dissolve sodium nitrate in water. Then using a ni-chrome wire, clean it in hydrochloric acid, dip the clean wire intoi the solution. Then pass the wire through a bunsen flame. The pale blue flame, will become bright yellow. Different metal ions produce different flame colours. Lithium = red Potassium = lilac Copper = Blue/green
How would you measure the brightness of light being reflected by an object?
by using a photometer

Test for sodium chloride?
If you have the solid of whatever your testing and you burn it (flame test) it will burn with an orange flame if sodium is present. To establish whether it is sodium CHLORIDE, ad a solution of what your testing to silver nitrate and it should form a white precipitate if it's sodium chloride.
How do you test for sodium ions and potassium ions when both are present?
One way to test for sodium ions and potassium ions when both are present is to use flame tests. Each ion produces a unique colored flame when burned. Another method is to use ion-selective electrodes that can differentiate between sodium and potassium ions based on their specific affinity for the electrodes. Separation techniques such as ion exchange chromatography can also be used to separate and quantify sodium and potassium ions.
What color flame would potassium ions make using sodium and potassium ions?
Potassium ions typically produce a lilac or light pink flame color when burned. When mixed with sodium ions, the flame color might have a slightly different hue due to the presence of both elements, but it would still be in the violet range of the color spectrum.
