K2CO3 breaks up to give 2 K+1 ions and 1 Carbonate ion or 3 ions.
Na2SO4 gives 2 sodium ions and 1 sulfate or 3 ions so 3 moles gives 9 moles of particles.
The change in freezing pt is a lowering and is Ksub f X molality of particles in the solution.
K for water is 1.86 degrees per molal
So you take K X moles particles/Kg of solvent to get the freezing pt depression..
Boiling pt is elevated and done the same way except the K is .52 degrees / molal of particles.

How do you prepare 50 percent solution of potassium carbonate?
Dissolve 50 g of potassium carbonate in 100 mL of water at 20 0C.
What is made when iron sulphate and sodium carbonate are mixed?
when their solution are mixed iron carbonate solid and solution of sodium sulphate is produced..
What is the use of potassium carbonate in the preparation of cochineal solution?
synthesized the c olor of cochineal solution because of carbon dioxide
What happens when you add calcium chloride to potassium carbonate?
When you add calcium chloride to potassium carbonate the products will be solid calcium carbonate and aqueous potassium chloride. The chemical equation for this reaction is CaCl2(aq) + K2CO3(aq) --> 2KCl(aq) + CaCO3(s). This type of reaction is called a double replacement/displacement reaction.
Mercuric chloride and potassium iodide?
Reddish precipitate of Mercuric iodide and clear solution of Potassium chloride is produced
Is it safe to eat potassium bicarbonate and sodium bi-carbonate solution?
Not directly. However there are edible products made with very small amount of this solution. By the way it's "Potassium Carbonate and Sodium Bi-Carbonate solution" AKA: alkaline water. Not Potassium Bi-carbonate.
How do you prepare 50 percent solution of potassium carbonate?
Dissolve 50 g of potassium carbonate in 100 mL of water at 20 0C.
What is the ionic compound K2CO3?
K2CO4 is a misspelling of the correct formula for potassium carbonate, which is K2CO3. This is a white salt that can be dissolved in water to form a alkaline solution by dissolution of the molecule into potassium ions (K+) and carbonate ions (CO3 2-). Note that CO4 would have 4 oxygen bonds to the carbon, which is not a very stable molecule and would not have a 2- charge.
Why do we add potassium carbonate during caffeine extraction?
Tannins are neutralized by potassium carbonate, remain in the water solution and caffeine is easily extracted with methylene chloride.
What is made when iron sulphate and sodium carbonate are mixed?
when their solution are mixed iron carbonate solid and solution of sodium sulphate is produced..
What is the formula for potassium carbonate dihydrate?
KHCO3 also called potassium bicarbonate In solution ions: K+ and HCO3-
What is the correct formula for potassium carbonate?
the formula of potassium carbonate is k2co3 because the valency of potassium (k1+) valency of carbonate is (co32-) interchange the valencies and don't put the signs then it will become (k2co3) so the formulae of potassium carbonate is k2co3
What is the use of potassium carbonate in the preparation of cochineal solution?
synthesized the c olor of cochineal solution because of carbon dioxide
Dilute hydrochloric acid is added to a solution of potassium carbonate?
2hcl- + k2co3====>2h2co3+2kcl
What happens when you add calcium chloride to potassium carbonate?
When you add calcium chloride to potassium carbonate the products will be solid calcium carbonate and aqueous potassium chloride. The chemical equation for this reaction is CaCl2(aq) + K2CO3(aq) --> 2KCl(aq) + CaCO3(s). This type of reaction is called a double replacement/displacement reaction.
What observations do you make when you react potassium hydroxide with sodium carbonate?
You get a double decomposition reaction, producing sodium hydroxide and potassium carbonate, but actually there is no real reaction; the four substances remain in perfect equilibrium in solution.
What colourless gas is produced when hydrochloric acid solution is added to sodium carbonate?
Carbon dioxide gas is produced when any strong acid is added to a metal carbonate.
