We should first look at the nature of the compound. Its sodium carbonate, that is a salt formed from a strong base (that's Na OH - sodium hydroxide) and a weak mineral acid (that's carbonic acid). So we know that bases turn moist red litmus blue, similarly in this salt, the moist red litmus should turn red as the characteristic of the strong base part of this salt overpowers the weak acid part of it.
What else can I help you with?
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.
How many grams of sodium are in 3 moles of sodium carbonate (Na2CO3) Give your answer to the nearest gram.?
3 x 2 x 23 = 138g
What would you observe if you mixed sodium carbonate and water?
If you mix sodium carbonate and water, you would observe that the sodium carbonate dissolves in the water. This is because sodium carbonate is highly soluble in water. The solution may also become slightly warm due to the dissolution process.
How would beryllium react with sodium carbonate?
Beryllium would react with sodium carbonate to form beryllium carbonate and sodium oxide. This is a double displacement reaction in which the ions from each compound swap places to form the new compounds. Beryllium carbonate is insoluble in water and would precipitate out of solution.
How would you separate water sodium carbonate and calcium carbonate?
To separate water, sodium carbonate, and calcium carbonate, you could first evaporate the water to leave behind the dry sodium carbonate and calcium carbonate. Next, you could use solubility differences to further separate the sodium carbonate and calcium carbonate; calcium carbonate is insoluble in water while sodium carbonate is soluble. So, you could dissolve the mixture in water, filter it to remove the calcium carbonate, and then evaporate the water to obtain the sodium carbonate.
What colour does litmus indicator turn when put in sodium hydrogen-carbonate?
When litmus indicator is put in sodium hydrogen-carbonate (a mild base), it turns blue. Sodium hydrogen-carbonate, also known as sodium bicarbonate, has a basic pH, which causes the blue color change in the litmus paper. In acidic solutions, litmus would turn red, but in this case, the basic nature of sodium hydrogen-carbonate results in a blue coloration.
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.
If litmus was added to washing up powder what colour would it change to?
If litmus paper is added to washing up powder, it would typically turn blue, indicating that the washing up powder is alkaline (basic). Most washing up powders contain sodium carbonate or other alkaline substances, which raise the pH and cause the blue color change in blue litmus paper. If red litmus paper is used, it would remain red, confirming the basic nature of the solution.
What reaction can be performed to tell the difference between sodium chloride and sodium hydroxide?
A litmus test is one way of comparing. Sodium Chloride is a neutral salt and so would have no effect on litmus. Sodium Hydroxide is a base, and would turn litmus blue.
Sodium is readily oxidized by oxygen gas if the product of the reaction were dissolved in water what would be the color the litmus for a litmus test?
The product of the reaction between sodium and oxygen is sodium oxide, which forms when sodium oxidizes in the presence of oxygen. Sodium oxide is a basic oxide and would turn red litmus paper blue, indicating it is basic.
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.
How many grams of sodium are in 3 moles of sodium carbonate (Na2CO3) Give your answer to the nearest gram.?
3 x 2 x 23 = 138g
What indicator in titration of sodium carbonate solution against hydrochloric acid would give a complete neutralization?
The indicator methyl orange can be used in the titration of sodium carbonate solution against hydrochloric acid to give a complete neutralization. At the endpoint, when all the carbonate ions have reacted to form bicarbonate ions, the solution will turn from yellow to pink.
What would you observe if you mixed sodium carbonate and water?
If you mix sodium carbonate and water, you would observe that the sodium carbonate dissolves in the water. This is because sodium carbonate is highly soluble in water. The solution may also become slightly warm due to the dissolution process.
What colour would blue litmus paper change to in vinegar?
Because Vinegar is an acid, the litmus paper would turn red
What will be the effect of sodium hydroxide in blue litmus paper?
Sodium hydroxide is a strong base, so it will turn blue litmus paper to red. This color change is due to the alkaline nature of sodium hydroxide which reacts with the blue litmus paper to change its color.
How would beryllium react with sodium carbonate?
Beryllium would react with sodium carbonate to form beryllium carbonate and sodium oxide. This is a double displacement reaction in which the ions from each compound swap places to form the new compounds. Beryllium carbonate is insoluble in water and would precipitate out of solution.
