what will be observed when this mixture is added to sodium carbonate solution?

The ester, methyl propionate is formed in this reaction.\nA sodium carbonate soln will neutralize any unreacted acid...the salt formed and methanol are soluble in water, but the ester is not...so it so it will rise to the top as a separate layer.\nYou will also note the fruity odor of the ester.

Not really, no.  CO2 is carbon dioxide, and sodium is a light metal that usually exists as a highly soluble cation.

H2SO4 + 2NaOH ----> 2H2O + Na2SO4\n\nYOU MUST SEPARATE AND CANCEL THE COMMON IONS (AQUEOUS ONES)

use sodium hydrolic solution

it's true that sodium carbonate CaCO3 can absorb the water as crystall water, but do not forget that the carbonate ion from the salt will react with the un absorbed water forming H2CO3 that will soon "brake" in to water (again) and carbon dioxide. in my experinece it is best if you use sodium sulfate anhydrous instead of sodium carbonate.

Baking soda added to water raises the temperature slightly.\n\nBaking soda and water is exothermic and so the water gets a little warmer. This is because the binding energy of the chemical bonds of the products has an excess over the binding energy of the components. Therefore, energy is released and the water warms up.\n\n\nBaking soda is NaHCO3 and water is H2O. Added together you get NaOH and H2CO3 which are sodium hydroxide and carbonic acid. \n\nCarbonic acid is the fizz in soda. Eventually the mixture releases CO2 gas when the H2CO3 breaks down into H2O and CO2. The solution of H2O and CO2, if left alone uncorked, will lose its fizz. The water CO2 mixture will cool off slightly when the fizz (CO2) is released because the CO2 takes some energy with it. As the water evaporates it cools off because the warm molecules of water evaporate first! That's right! The warm ones!

When in the bottle or can the solution is in equilibrium with the partial pressure of C02 equal to the pressure in the can. When the can is opened the pressure in the can drops (the ffffft or hiss sound you hear) and now the partial pressure of C02 in the soda solution is greater than the atmospheric pressure. This results in C02 coming out of solution, which causes bubbles to form. The bubbles represent a separate phase, which is a heterogeneous mixture rather than the homogeneous mixture prior to opening.\nNote that the CO2 levels does not completely equilibrate upon opening. Once the solution has come nearly to equilibrium (re CO2), the soda is said to have 'gone flat' and is no longer fizzy.\n\nI'm not sure the presence of oxygen has anything to do with this phenomenon.

Adding sulphuric acid and sodium hydroxide respectively??

When what is mixed is not fully disolved into the liquid medium.  It usually settles.  A cenrifuge will not separate out the components that are not part of the solution.

If when you mix the two together the solution turns clear, you have a solution.  If it makes a cloudy mixture, or if there is visible solid on the bottom, you have a heterogeneous mixture, or a non-uniform mixture, which is not a solution.

Go to the local grocery store, and look for "washing soda" in the cleaning supplies section.  If you look at the fine print on the box/bag, it may say "Sodium Carbonate" or "Sodium Carbonate Decahydrate" \n\nHave fun, and good luck with the experiment!

sodium chloride and water

u must keep the the solution in 37C incubator after adding SDS, so that the surfactant SDS wont make crystals it will take sm time but they will dissapear. but will reappear if u keep it at low temp....so before using transfer it to 37C

Check on the internet for the ratios used by comercial factories, then prepare a solution from glycol and water in the given proportion. That's all!!!

mix it...let NaCl dissolve in water...then let the mmixture evaporate or perhaps bring the mixture into a boil 'til you can see the formation of crystals...   try it... i've encountered such experiment in my chemistry class... im not quite certain of the procedures though...it's two years ago...cant remember it well...^_^

The answer given earlier is more feasible i.e decomposing sodium hydrogen carbonate, the equation thus:\n\n2NaHCO3 --> Na2CO3 + CO2 + H2O\n\nBut, the decomposition for your specific enquiry thus:\nNa2CO3 --> CO2+Na2O\n\nI hope this helps
