Why sodium carbonate is used in preparation of thiosulphate solution?
To ensure the stability of the solution
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 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 does a sodium hydrogen carbonate indicator do?
Sodium hydrogen carbonate is used as an indicator of pH or as a test for the concentration of carbon dioxide. For the preparation of the solution see the link below.
How many moles of potassium carbonate are in 10.0mL of a 2.0 M solution?
Ten milliliters is a hundredth of a liter. So in a two molar solution, you would have .02 moles in 10 ml.
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.

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 the use of potassium iodide in the preparation of iodine solution?
somehow. the potassium iodide act as a acidifying agent,
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
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.
Preparation of 0.1 normal solution of sodium carbonate in 1 liter?
52.5g of Na2CO3 in 1 litre water
