What is the colour of sodium carbonate?
white
What is colour of an aqueous solution of sodium carbonate in presence of a drop of phenolphthalein?
The color of an aqueous solution of sodium carbonate in the presence of phenolphthalein would be pink. Phenolphthalein turns pink in basic solutions with a pH above 8.2. Sodium carbonate is a basic compound that will cause the phenolphthalein indicator to change color to pink.
What is the colour of aluminium carbonate solution?
Aluminium carbonate solution is usually colorless.
Why sodium hydroxide solution contains sodium carbonate?
Sodium hydroxide solution may contain sodium carbonate due to the absorption of carbon dioxide from the atmosphere. Sodium hydroxide can react with carbon dioxide to form sodium carbonate over time, especially if the solution is exposed to air. This can result in a small amount of sodium carbonate being present in the solution.
What will happen if a solution of sodium hydrogen carbonate heated?
When a solution of sodium hydrogen carbonate is heated, it will decompose to form sodium carbonate, water, and carbon dioxide gas. This decomposition reaction is characterized by effervescence due to the release of the carbon dioxide gas.
What colour does sodium carbonate go?
Pure sodium carbonate is white.
What is the colour of sodium carbonate?
white
What does 1M solution of sodium carbonate mean?
A 1M solution of sodium carbonate means that it contains 1 mole of sodium carbonate dissolved in 1 liter of solvent (usually water). This concentration is used in chemistry to describe the amount of the solute (sodium carbonate) present in the solution.
How benedict solution prepared?
A Benedict's solution is a solution of sodium citrate, sodium carbonate and copper sulphate, whose colour changes from blue to yellow to red in the presence of reducing sugars such as glucose.
What is the colour change when litmus paper is placed in a solution of sodium hydrogen carbonate?
Red to blue due to hydrolysis
How Make up a 7.5 percent solution of sodium carbonate in water?
To make a 7.5% solution of sodium carbonate in water, add 7.5 grams of sodium carbonate to 100 mL of water and stir until the sodium carbonate is completely dissolved. This will give you a 7.5% (w/v) solution of sodium carbonate.
What is colour of an aqueous solution of sodium carbonate in presence of a drop of phenolphthalein?
The color of an aqueous solution of sodium carbonate in the presence of phenolphthalein would be pink. Phenolphthalein turns pink in basic solutions with a pH above 8.2. Sodium carbonate is a basic compound that will cause the phenolphthalein indicator to change color to pink.
What is made when iron sulphate and sodium carbonate are mixed?
When iron sulfate and sodium carbonate are mixed, iron carbonate and sodium sulfate are produced. Iron carbonate is a solid precipitate that can be formed during the reaction, while sodium sulfate remains in solution.
What is the colour of aluminium carbonate solution?
Aluminium carbonate solution is usually colorless.
Why is sodium carbonate added to solution before Benedicts test is performed?
Sodium carbonate is added to increase the pH of the solution.
Is sodium carbonate solution an element a compound or a mixture?
Sodium carbonate solution is a compound. It is composed of sodium ions (Na+) and carbonate ions (CO3^2-). When dissolved in water, these ions separate from each other but remain chemically bonded as a compound.
Why sodium hydroxide solution contains sodium carbonate?
Sodium hydroxide solution may contain sodium carbonate due to the absorption of carbon dioxide from the atmosphere. Sodium hydroxide can react with carbon dioxide to form sodium carbonate over time, especially if the solution is exposed to air. This can result in a small amount of sodium carbonate being present in the solution.
