How much time is required to melt sodium chloride using Bunsen burner?
Wiki User
∙ 11y ago
The time it takes to melt sodium chloride using a Bunsen burner can vary based on factors such as the heat intensity of the burner, the amount of sodium chloride being melted, and the starting temperature of the salt. Generally, it may take a few minutes to melt sodium chloride completely using a Bunsen burner.

Is heating sodium chloride with a Bunsen burner a chemical change?
Heating sodium chloride with a Bunsen burner is a physical change because it only involves a phase change (from solid to liquid) without altering the chemical composition of the substance.
When heated with a Bunsen burner does sodium carbonate decompose?
Yes, when heated with a Bunsen burner, sodium carbonate (Na2CO3) decomposes to form sodium oxide (Na2O) and carbon dioxide (CO2).
What is the colour of the flame of a Bunsen burner when you put sodium glutamate on it?
The flame color of a Bunsen burner with sodium glutamate is typically a bright yellow due to the presence of sodium ions in the compound. Sodium compounds are known to produce intense yellow flame colors when burned.
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.
Why does sodium carbonate not decompose when heated using a Bunsen burner?
Sodium carbonate does decompose when heated, it undergoes thermal decomposition to form sodium oxide (Na2O), carbon dioxide (CO2), and water (H2O). However, the decomposition of sodium carbonate is not easily noticeable when using a Bunsen burner as the high temperature and rapid combustion of the gas can mask the decomposition reaction.

When heated with a Bunsen burner does sodium carbonate decompose?
Yes, when heated with a Bunsen burner, sodium carbonate (Na2CO3) decomposes to form sodium oxide (Na2O) and carbon dioxide (CO2).
What compound when heated over a Bunsen burner does not decompose?
Sodium Carbonate
Where does electron goes when sodium is burnt in Bunsen burner?
Goes to the oxygen.
What is the colour of the flame of a Bunsen burner when you put sodium glutamate on it?
The flame color of a Bunsen burner with sodium glutamate is typically a bright yellow due to the presence of sodium ions in the compound. Sodium compounds are known to produce intense yellow flame colors when burned.
Name a metal carbonate that does not decompose when heated with a Bunsen burner flame?
Sodium Carbonate
Name a metal carbonate that dose not decompose in a Bunsen burner flame?
sodium carbonate
Does sodium carbonate decompose when heated by a Bunsen?
Yes, sodium carbonate decomposes when heated by a Bunsen burner. At high temperatures, sodium carbonate breaks down into sodium oxide and carbon dioxide gas through a process called thermal decomposition.
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 metal does not decompose when heated with a Bunsen burner?
Tungsten is a metal that does not decompose when heated with a Bunsen burner due to its high melting point of 3422°C. This property makes tungsten ideal for use in the filament of incandescent light bulbs.
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.
Sodium chloride is mixed with sodium hydroxide?
When sodium chloride is mixed with sodium hydroxide, a chemical reaction takes place to form sodium chloride and water. This reaction is a simple double displacement reaction where the cations and anions switch partners to form new compounds.
