What else can I help you with?
What would happen when blue litmus is put in sodium carbonate solution?
Blue litmus turns red in acid. Sodium carbonate solution is alkaline (basic), so nothing will happen when blue litmus is put into this. Red litmus will turn blue if added to sodium carbonate.
What is the action of litmus with aqueous solution Na2CO3?
Red litmus paper turn blue in basic solutions; sodium carbonate solution is basic.
Why iron does not displace sodium from salt solution?
Iron does not displace sodium from a salt solution because it is not reactive enough. Iron does, however, displace Cu from a copper sulphate solution.
Why are fehling solution A and B kept separately?
fehling a is copper sulphate and fehling b is alkaline solution of sodium pottasium tartarate
What are the functions of mercuric chloride sodium sulfate and sodium chloride in Hayem's solution?
Hayem's solution. This is an isotonic fluid which consists of the folIowing constituents (in g/100 ml):sodium chloride 0.5, sodium sulphate 2.5 and mercuric chloride 0.25. The sodium sulphate discourages clumping of the erythrocytes and the mercuric chloride is a preservative.
How do you distinguish between copper sulphate solution sodium chloride solution sodium nitrate solution or sodium sulphate solution?
copper sulphate solution-blue sodium chloride (salt) solution-clear sodium nitrate solution- white to clear sodium sulphate solution- white copper sulphate solution-blue sodium chloride (salt) solution-clear sodium nitrate solution- white to clear sodium sulphate solution- white
What happens if red litmus and blue litmus is dipped in sodium chloride?
Sodium chloride water solution is neutral.
What is observed when sodium sulphate solution is added to barium chloride?
A white precipitate of barium sulphate is formed when sodium sulphate solution is added to barium chloride solution. This is due to the formation of an insoluble salt, barium sulphate, which appears as a white solid in the solution.
What is the colour of sodium sulphate solution by chemists?
The solution is colorless.
What would happen when blue litmus is put in sodium carbonate solution?
Blue litmus turns red in acid. Sodium carbonate solution is alkaline (basic), so nothing will happen when blue litmus is put into this. Red litmus will turn blue if added to sodium carbonate.
What color does sodium chloride give on litmus paper?
Sodium chloride solution is neutral.
What is the molarity of a solution made by dissolving 23.4g of sodium sulphate in enough water to make up a 125ml solution?
To find the molarity, first calculate the number of moles of sodium sulphate using its molar mass. Sodium sulphate's molar mass is 142.04 g/mol. Next, divide the number of moles by the volume in liters (125 ml = 0.125 L) to get the molarity. This will give you the molarity of the sodium sulphate solution.
What is the action of litmus with aqueous solution Na2CO3?
Red litmus paper turn blue in basic solutions; sodium carbonate solution is basic.
Where does the sodium sulphate go when copper sulphate mixes with sodium hydroxide?
Nowhere. I assume you are talking about mixing solutions. The sodium ions and sulpahate ions remain in solution.
What is the composition of fehling's solution?
Fehling's solution is made up of two separate solutions: Fehling's A (copper sulfate solution) and Fehling's B (potassium sodium tartrate and sodium hydroxide solution). When combined in equal parts, these solutions are used to test for the presence of reducing sugars like glucose in a chemical sample.
Why does strontium sulfate becomes less soluble in an aqueous solution when sodium sulfate is added?
Sodium sulphate increases the concentration of sulphate ions. So strontium sulphate solubility decreases.
Does sodium hydroxide turn litmus solution purple?
yes, it turns in purple or a very light pink-ish purple color
