Sodium carbonate equation?
The chemical formula of sodium carbonate is Na2CO3. A solution hasn't a formula.
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.
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

Preparation of standard solution and standardization of hydrochloric acid Objective : To prepare a standard solution of sodium carbonate and use it to standardize a given solution of dilute hydrochloric acid. Introduction : Anhydrous sodium carbonate is a suitable chemical for preparing a standard solution (as a primary standard). The molarity of the given hydrochloric acid can be found by titrating it against the standard sodium carbonate solution prepared. The equation for the complete neutralization of sodium carbonate with dilute hydrochloric acid is Na2CO3(aq) + 2HCl(aq) → 2NaCl(aq) + CO2(g) + H2O(l) The end-point is marked by using methyl orange as indicator. Chemicals :solid sodium carbonate, 0.1 M hydrochloric acid
Why anhydrous sodium carbonate is a primary standard?
na2co3 is primary standard,because,molarity remains same with time,and it is of high molecular weight

What happens when you mixed the magnesium chloride solution with the sodium cabonate solution?
MgCl2 + Na2CO3 = 2NaCl + MgCO3
What is Secondary standard solution in volumetric analysis with example?
Primary standard is a chemical entity available with highest purity and stability with high molecular weight. e.g. KHP, NaCl, Calcium salt used in standardisation of volumetric solution. Secondary standards are compounds used in analysis after evaluation against primary standards. e.g.- NaOH VS, Sodium thiosulphate VS

What salt is produced in pH rainbow tube?
The solution must contain Na2CO3 and NaHCO3.
Which solution turns cloudy when it react with a gas?
i)NaOH + FeCl3 ii) Na2CO3 + CaCl2
A 0.200M solution of sodium carbonate Na2CO3 is made by dissolving 5.30g of the solid in water and making up the mark in a standard flask What volume must the flask be?
Flask is something that holds the sweeet nectar of alcohol
