Boiling this is done to remove ALL carbon dioxide (as gas) from the solution, before titrating the HCl-excess 'back' with titrant sodium hydroxide. Otherwise CO2 is disturbing the reaction at the end point of this backtitration at pH = 7 to 8 indicated by phenolphtaleine)

Na2CO3.xH2Oaq + 2HClaq --> 2NaClaq + H2Oliq + CO2(gas) + H+aq,(excess)

(Don't forget to cool down after boiling)

OH- + H+(excess) ==> H2O

OH- + CO2 |-o-| 'nill'

(= no reaction of CO2 to form HCO3-, which is formed at pH = 7 to 8)

What chemicals do you add together to make calcium chloride?

Calcium chloride is typically produced by reacting hydrochloric acid with calcium carbonate or calcium oxide. This reaction forms calcium chloride, water, and carbon dioxide. Additional purification steps may be required to obtain the desired purity of calcium chloride.


Why chalk does not react with HCl?

Chalk is primarily made of calcium carbonate, which is a stable compound. When chalk comes in contact with hydrochloric acid (HCl), it does not react because calcium carbonate is insoluble in acidic solutions. This lack of reactivity is due to the stable structure of calcium carbonate molecules.


What is the product of sodium hydrogen carbonate and dilute hydrochloric acid?

NaHCO3 + HCl(l) ---> Na(aq) + H2 + Cl(aq) + CO2. The products are aqueous sodium and chloride (though not technically correct, they are often put together in most descriptions), hydrogen gas and carbon dioxide.


How is tin(IV) chloride made in the lab?

Tin(IV) chloride is typically made by reacting tin with chlorine gas or hydrochloric acid. One common method involves heating a mixture of tin and chlorine gas together to produce tin(IV) chloride. Another method involves reacting tin with hydrochloric acid and then evaporating the resulting solution to obtain tin(IV) chloride.


What is the word equation for the reaction of sodium carbonate with hydrochloric acid?

The word equation for the reaction between Sodium carbonate and hydrochloric acid is: Sodium carbonate + Hydrochloric acid = sodium chloride + carbon dioxide + water The balanced equation is: Na2CO3(aq) + 2HCl(aq) --> 2NaCl(aq) + CO2(g) +H2O(l) All the acid and the carbonate is used up in the reaction giving a salt, carbon dioxide and water. This is a neutralisation reaction.

What does Calcium carbonate plus hydrochloric acid make when reacted together?

It makes calcium chloride,water and carbon dioxide


Can magnesium carbonate be made as a precipitate by reacting together magnesium sulfate and calcium carbonate?

The proposed method of making magnesium carbonate can not be accomplished from solutions in water, because the solubility of calcium carbonate in water is so low that it can not furnish a sufficient concentration of carbonate ions to exceed the solubility product constant for magnesium carbonate.

What else do you need apart from oxygen to make CuCO3?

Copper and carbon along with oxygen make up copper(II) carbonate. However you cannot make it simply by mixing them together. A possible pathway might be to get to sodium carbonate perhaps CO2 + NaOH might be the way and then make some copper sulfate by reacting it with H2SO4, mix your sodium carbonate solution with copper sulfate solution and copper carbonate should precipitate out.

How do you make a dry sample of magnesium chloride crystals from magnesium carbonate and hydrochloric acid?

Firstly, you need to mix the two solutions together to form magnesium chloride, carbon dioxide and water. since carbon dioxide is a gas there is no need to chemically remove it. then you should evaporate the water from the solution and heat the salt slowly to crystalize the solution.


What products do you get when you mix hydrochloric acid and copper carbonate together?

Any acid will react with any carbonate to produce carbon dioxide and water. The other product is an ionic compound of the remaining ions, in this case copper chloride. (If the problem requires you to include phase labels, you also have to decide whether the ionic product will be soluble in water or not.)


What do you call the two chemicals that react together in antacid tablets?

The two chemicals that react in antacid tablets are typically aluminum hydroxide and magnesium hydroxide. These chemicals help to neutralize stomach acid and provide relief from heartburn and indigestion.
