Percentage of Na 2 CO 3 by weight in the soda ash Unknown #244 was calculated to beĢ2%, (see application of Eq. Mass of Na 2 CO 3 in each sample was determined to be 0 g and, finally, the Titrant required to neutralize this amount was found to be 12 mL. The average mass of sodaĪsh used in the titration procedures was found to be 0 g.

Trial #1 Initial Volume HCl (mL) Final Volume HCl (mL)37 25 Total Volume of Titrant Used (mL)11 Total mass of Soda Ash Used (g)0. The test showed that the data from all three trials fell within the acceptable range ofĬritical values for G, and all values were kept for analysis, (see Table 3, Grubbs Test, The precision of the results to determine if any outlying data points should be discarded. With the raw data from the three trials compiled, the mean and standard deviation wereĬalculated using Microsoft Excel’s data analysis. Mean and Standard Deviation, Titration of Unknown # MHCl(Na2CO3), was then determined (using Eq. Sample was found and averaged, the molarity of the standardized HCl solution, Once the volume of HCl titrant required to neutralize the Solution was then titrated three times using 0 g Na 2 CO 3 and bromocresol green Therefore, a standardized preparation of 0 M HCl was then made by taking 8 mL ofĬoncentrated ( ≈12 M) HCl and adding it to 1 L of deionized water (DI). To show 2 molar equivalents of HCl for every 1 mole of Na 2 CO 3, (see Eq. A balanced chemical equation for the reaction was noted In order to carry out the titration of the soda ash samples, it was necessary to Preparation of a Standardized HCl Solution Soda ash is still one of the world’s most i 4 mportant industrialĬhemicals, and its components play a key role in many modern manufacturingĪ sample of soda ash was analyzed by direct titration to determine the weight Evidence also exists of its use as a drying agent in mummification,Īs a medicinal treatment, often for headaches, and as a leavening agent used in theīaking of bread. Sodium carbonate was long prized for its cleaning properties, and it became an integral There have been many non-industrial uses for soda ash throughout history, as well. Natron, and this is the origin of “Na” being used as the chemical symbol for sodium. Nile left soda crystals on the flood plain as it dried. In the ancie 2 nt world, sodaĪsh was harvested in Egypt’s Natron Valley as the annual receding floodwaters of the The manufacturing processes of ceramics and glassware. Evidence of its important role in manufacturing has been found asįar back as the ancient Egyptian and Roman empires, where it was used by artisans in The sodium carbonate present in soda ash has been treasured by mankind for Sodium carbonate, Na 2 CO 3, a white, anhydrous granulated material with a high alkaline Soda ash is a mixed, naturally-occurring compound thatĬontains several reagents that are vital to manufacturing and industry.
