methods for detecting carbonate ion
The above gas is passed through 1ml of limewater taken in a testtube and shaken well
Observation
Lime water turns milky & presence of carbonate is confirmed

∙ 11y agoAdd a good amount of hydrochloric acid (HCl) to it!
Sodium Carbonate has the formula: Na2CO3
and Sodium Hydroxide has the formula: NaOH
look what happens when we add HCl to each
Na2CO3(Sodium Carbonate) + 2HCl ---> 2NaCl + H2O + CO2
* the CO2 in that equation is carbon dioxide, a gas. So your solution will bubble with these carbon dioxide gas bubble. But be careful! The 2 in front of the HCl in that equation means you have to add enough HCl for the carbon dioxide to form or else nothing will happen, so be generous with it :).
Now for the Sodium Hydroxide
NaOH + HCl ---> H2O + NaCl
* this equation only produces water (H2O) and dissolved salt (NaCl). So there will be no bubbling in this reaction.
** So if you add a good amount HCl to the substance and it bubbles its Sodium Carbonate, and if it doesn't bubble, it's Sodium Hydroxide. Hope that helped.

2. Sodium carbonate is formed from two ions the Na+ ions and the CO3 2- ion identifying it from other carbonates can be hard but it should produce the orange sodium flame in a bunsen burner

∙ 13y agoNo, sodium hydroxide is NaOH. It is a strong base made of sodium, hydrogen and oxygen.
Sodium carbonates is Na2CO3. It is a weak base and is composed of sodium, carbon, and oxygen.

Why sodium hydroxide solution contains sodium carbonate?
Water reacts with carbon dioxide in the air to form small amounts of carbonic acid. In a sodium hydroxide solution, this reacts again to form sodium carbonate.
What is sodium acetate made?
Sodium acetate is obtained from the reaction of the acetic acid with sodium hydroxide, sodium carbonate, etc.
How do you distinguish sodium hydroxide and sodium acetate?
To test presence of Sodium ions, do a flame test: color observed: golden yellow. To test presence of carbonate or hydrogen carbonate ions: Take some of the sodium hydrogen carbonate in a dry test tube. Heat the test tube and bubble the gas through limewater. Limewater turns milky. Carbonate or hydrogen carbonate ions present. To distinguish between carbonate and hydrogen carbonate: Add indicator solution. If colour of solution turns green, pH is 7-8, hydrogen carbonate ions are present. If colour of solution turns blue, pH is 12-13, carbonate ions are present. -Iberuz
What is the Name for NaOH?
The chemical name is Sodium Hydroxide. It is made of Na+ ions and OH- ions.
What is sodium reactive with?
sodium is white and metallic it is a metal that is essential for life. sodium carbonate reacts with sodium hydrogen sulfate to create a rapid reaction. sodium also reacts with aluminium hydroxide
What are three examples of base?
Sodium hydroxide Sodium carbonate Sodium bicarbonate
Can you detect a mixture of sodium hydroxide sodium carbonate and sodium bicarbonate?
yes
What has the highest pH value acetic acid or sodium hydroxide or sodium carbonate or sulphuric acid?
sodium hydroxide
What are some common items that sodium is in?
Examples: sodium chloride, sodium carbonate, sodium hydrogen carbonate, sodium hydroxide, sodium sulfide, sodium acetate, sodium bromide, borax, etc.
Why sodium hydroxide solution contains sodium carbonate?
Water reacts with carbon dioxide in the air to form small amounts of carbonic acid. In a sodium hydroxide solution, this reacts again to form sodium carbonate.
The fourmula for soda?
Soda is sodium hydroxide (NaOH) or sodium carbonate (Na2CO3).
What is sodium acetate made?
Sodium acetate is obtained from the reaction of the acetic acid with sodium hydroxide, sodium carbonate, etc.
What is the scientific name for caustic soda?
The scientific name for caustic soda is sodium hydroxide with the chemical formula NaOH.
What is the molecular sodium carbonate and sodium hydroxide?
Sodium carbonate has sodium, carbon and oxygen in it, and the molecular formula is NaCO. Sodium hydroxide is consists of the elements sodium, oxygen and hydrogen and it has the molecular formula NaOH. One of the common features of both these compounds are being alkali in aqueous medium.
