# To make a standard solution of Sodium Carbonate and work out it's molarity.

Extracts from this document...

Introduction

Making a Standard Solution Aim To make a standard solution of Sodium Carbonate and work out it's molarity. Key points about a standard solution The characteristics of a standard solution are * Must be obtainable in a highly pure state * Must be stable to heat and light, both as a solid and in solution. * Should have a high molar mass * High solubility in H2O Equipment/Safety * Volumetric flask * Sodium Carbonate powder. * Spatula * Deionised water. * Safety goggles * Lab coat * Analytical balance * Weighing bottle * Volumetric flaks stopper. ...read more.

6. Replace the stopper and shake the volumetric flask vigour sly. 7. Now calculate the Morality of your solution Calculations I am now going to work out the molarity of Na2CO3. Na2CO3 (23 X 2)+12(16 X 3) 46 +12+48 106 Moles= Mass/R.M.M 0.0241= 2.5555/106 Concentration =Moles /Volume 0.0964M= 0.0241/ 0.25 Conclusion My aim was to make a standard solution and to work out its molarity As you can see above I have worked out the molarity.the moarity of my sodium carbonate solution is 0.0964M. Titration using Na2CO3 and HCl Aim The aim of this experiment is to find the end point of Sodium Carbonate and Hydrochloric acid Equipment/Safety equipment/Chemicals * HCl * Sodium Carbonate * ...read more.

Conclusion

4. Fill your burette with HCl and read it to 2 decimal places 5. Titrate the alkali in the flask with the acid until the end point is reached. This is when the colour changes from yellow o orange. 6. Record the initial and final burette readings so you can determine the titre for each titration.
