Standardization of hcl solution with primary standard na2co3 solution?
solution containig (3.3)gm na2co3 .h2o in (15ml)
Sodium carbonate equation?
The chemical formula of sodium carbonate is Na2CO3. A solution hasn't a formula.
Why aqueous sodium carbonate solution is basic in nature?
Na2CO3 +H2O----->HCO3++OH-HERE HCO3- IS A WEAK ACID AND OH- IS A STRONG BASE
Which is more acidic nahco3 or na2co3?
na2co3 is more basic nahco3 is more acidic but both are bases.
Why is Na2CO3 alkaline in nature?
Because it contains sodium cations, which are strongly basic, and carbonate anions which are weakly acidic. So the basic ions win over acidic ions, making Na2CO3 alkaline(i.e. basic).
What is the action of litmus with aqueous solution Na2CO3?
Red litmus paper turn blue in basic solutions; sodium carbonate solution is basic.

How do you prepare 250ml 15m solution of naco3 in a volumetric flask do presume a solvent ie h20 but then you have to presume volumes and conc and because 15M wanted you cant use the flask to dilute?
Did you mean 250 mL of 0.15 M Na2CO3? (It's impossible to make a 15 M Na2CO3 solution, as Na2CO3 is not that soluble.) Yes, you can assume that this will be an aqueous solution. Steps. 1. Calculate the mass of solid Na2CO3 needed. 2. Place this mass of Na2CO3 in the volumetric flask. 3. Add some water and swirl to dissolve the Na2CO3. 4. Carefully add more water until the total volume of solution is 250 mL, as indicated by the line etched on the neck of the volumetric flask. 250 mL x 1 L x 0.15 mol Na2CO3 x 105.99 g Na2CO3 = 4.0 g Na2CO3 needed ........... 1000 mL ......... 1 L ..................1 mol Na2CO3
When 2.61 of solid Na2CO3 is dissolved is sufficient water to make 250 mL of solution the concentration of Na2CO3 is?
You need to mention the unit for 2,61.
What happens when you mixed the magnesium chloride solution with the sodium cabonate solution?
MgCl2 + Na2CO3 = 2NaCl + MgCO3
Why Na2CO3 is added to solution before Benedicts test is performed?
Sodium carbonate is added with the purpose to increase the pH of the solution.
Is methyl orange the indicator used in the titration of na2co3 against hcl solution?
yes it is
What salt is produced in pH rainbow tube?
The solution must contain Na2CO3 and NaHCO3.
