When dissolved in water, Na2CO3 dissociates into two ions. The carbonate can pull hydrogen ions away from water molecules, leaving hydroxide ions. The hydroxide ions are what causes the solution to be basic.

0.2g Na2CO3 dissolved into 25ml DI Water. Methyl Orange is used 2 to 3 drops is a indicator. then we take normal solution of 0.02N H2SO4 in beurate . note the volume consumed of H2SO4. put these value in formula formula N H2SO4= wt of Na2CO3 * volume of Na2CO3 used/ 53 * volume of H2SO4 consumed repeat this process

The pH of sodium carbonate solution is about 11.

A 0.5N Na2CO3 used in determining the concentration of an unknown HCl solution has a weight of 1.06 grams. To find the weight, you need to first find out how many moles there are by calculating molarity times volume.

It is a basic (alkaline) solution.

0.2g Na2CO3 dissolved into 25ml DI Water. Methyl Orange is used 2 to 3 drops is a indicator. then we take normal solution of 0.02N H2SO4 in beurate . note the volume consumed of H2SO4. put these value in formula formula N H2SO4= wt of Na2CO3 * volume of Na2CO3 used/ 53 * volume of H2SO4 consumed repeat this process

6.73g (1 mole of Na2CO3/106g) = 0.063mol/0.25L = 0.25M Na2CO3 2 moles of Na+ x 0.25M = 0.5M Na+ 1 mole of CO32- x 0.25M = 0.25M CO3

The pH of sodium carbonate solution is about 11.

Molarity = moles of solute/Liters of solution Or, for our purposes, Moles of solute = Liters of solution * Molarity Moles Na2CO3 = 10.0 Liters * 2.0 M = 20 moles Na2CO3 --------------------------

na2co3 is primary standard,because,molarity remains same with time,and it is of high molecular weight
