How Make up a 7.5 percent solution of sodium carbonate in water?
take 7.5 gram of sodium carbonate and dissovled in 100 ml of water..thats it.. this solution is called 7.5% sodium carbonate soultion.
What happens when sodium carbonate and vinegar are added?
I did this science practical at school i added half a teaspoon of sodium carbonate to 20 ml of vinegar. It fizzed up then after about ten seconds went down.
How do you prepare a primary standard solution of 0.0500 M sodium carbonate?
use the equation that is standard: 1000 ml 1 M solution= (MOLECULAR WEIGHT) X ml 0.05 M solution = ((MOLECULAR WEIGHT)*X*0.05)/1000
What is the molarity of the 5.60 mols of sodium carbonate in 1500 ml of solution?
Molarity is moles per litre. You need to divide the moles by 1500 and multiply by 1000. 5.6/1500*1000 is 3.73333 molar.
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 2 ml of HCL is added to sodium carbonate?
Firstly, they'll react each other forming sodium hydrogen carbonate and sodium chloride. If there is excess HCl, the sodium hydrogen carbonate would further react till sodium chloride and evolve carbon dioxide.
Need Help with my pH calculation?
1) 0.10 mol of solid sodium hydrogen carbonate and 0.20 mol of solid sodium carbonate are dissolved in the same beaker of water, transferred to a volumetric flask and made to 250.0 mL. The Ka for HCO3 - is 4.7 x 10-11. a) What is the pH of the resulting buffer? b) What is the pH of solution after 20.00 mL of 0.050 mol L-1 hydrochloric acid solution is added to 25.00 mL of the original solution? c)What is the pH of the resulting buffer after 0.040 g of solid sodium hydroxide is added to 25.00 mL of the original solution? 2) Plan how you would make 100.0 mL of a buffer solution with a pH of 10.80 to be made using only sodium carbonate, sodium hydrogen carbonate and water.Youshould specify the amounts of sodium carbonate and sodium hydrogen carbonate that you would use. ( the ration acid to base is 3:1)

How many grams is 10 mL of sodium carbonate?
Does not convert; milligrams (mg) and grams (g) are measures of weight or mass and mL (milliliters) is a measure of volume.
What is the molarity of 5.60 mol of sodium carbonate in 1500-mL of solution?
Molarity = moles of solute/Liters of solution ( 1500 mL = 1.5 Liters ) Molarity = 0.800 moles NaOH/1.5 Liters = 0.533 M sodium hydroxide ...
How do you prepare 10 percent Na2CO3 solution?
Mix 100 mL of a 1 N solution with 900 mL of distilled water.
Calculate the sodium ion concentration when 40.0 mL of 2.5 M sodium carbonate is added to 30.0 mL of 1.0 M sodium bicarbonate?
first of all, let's find the molecular formula for the two substances: Na2(CO3) and Na(HCO3). sodium carbonate has two Na atoms in each molecule and sodium bicarbonate has only one. now let's find the number of moles of sodium carbonate and sodium bicarbonate we have: 2.5M * .04L = .1mol 1M * .03L = .03mol we now know that there are .2mol (.1*2) of Na in sodium carbonate because there's two sodium ions in each sodium carbonate. And we know that there's 1 Na ion in each sodium bicarbonate, so we know it's just .03 mol Na in sodium bicarbonate. add those up: .2mol+.03mol = .23mol Na since Molar = mol/volume, we can find the volume of the whole solution: 30mL + 40mL=70mL or .07L .23mol/.07L is 3.29M

How do you prepare 100 mM Na carbonate bicarbonate buffer PH 9?
Insufficient information. The desired molarity or normality of the solution is required. For 100 mL of 1.0 molar sodium carbonate dissolve 10.59 grams of anhydrous sodium carbonate in 100 mL water.

How do you precipitate magnesium ion out of 50-mL of 21 M solution of magnesium nitrate?
Add something that magnesium will form an insoluble compound with. Sodium sulfate or potassium carbonate, maybe.
How do you prepare a primary standard solution of 0.0500 M sodium carbonate?
use the equation that is standard: 1000 ml 1 M solution= (MOLECULAR WEIGHT) X ml 0.05 M solution = ((MOLECULAR WEIGHT)*X*0.05)/1000
