Sodium hydroxide sodium carbonate

Answer 1

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

Answer 2

Sodium hydroxide (NaOH) is a strong base commonly known as caustic soda, while sodium carbonate (Na2CO3) is a salt that can act as a weak base. Sodium hydroxide is highly caustic and commonly used in industries for various purposes, while sodium carbonate is used in cleaning products, water treatment, and food production.

Answer 3

Add 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.

Answer 4

1.Carbonates release co2 when exposed to acids or other oxidising agents.

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

Answer 5

Weigh an exact amount and titrate with 0.1N HCl. The titration and subsequent calculation will indicate if you have sodium carbonate. While titrating it should give off Carbon dioxide which is also a good indication. Use Phenolphthalein as indicator.

Answer 6

Sodium carbonate: Na2CO3 , also known as soda.

Sodium hydroxide: NaOH , also know as lye.

Answer 7

No, 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.

Answer 8

Determine the number of moles of each. then % would be:

moles of one/total moles of both X 100%
