  1. Determine the concentration of lime water.

    2 Concentration of Limewater in mol dm?3: 25.0cm3 = 25.0 dm3 = 2.50*10?2 dm3 1000 2.82*10?@ mol dm?3 2.50*10?2 = 1.13*10?2 mol dm?3 Concentration of Limewater in g dm?3: Formula mass (Ca(OH)2)= 40.1+(16+1)*2 = 74.1g Concentration of Ca(OH)2= 74.1* 1.13*10?2 g dm?3 = 0.83733 g dm?3 = 0.84 g dm?3?

  2. CONCENTRATION OF LIME WATER

    in g dm?3: Formula mass (Ca(OH)2)= 40.1+(16+1)*2 = 74.1g Concentration of Ca(OH)2= 74.1* 1.13*10?2 g dm?3 = 0.83733 g dm?3 = 0.84 g dm?3? I conclude that my results are quite accurate as they are near to the 1g dm?3 estimate given to us.

    burette after I have rinsed the burette with the dilute Nitric acid. I will do this by putting a funnel at the top of the burette and pouring the Nitric acid from the volumetric flask. I will come at length of the burette and see if I have accurately filled the burette up until the desired value (meniscus).

    So if I were to use the phenolphthalein indicator then the end point (colour change) would be reached before the equivalence point (when the chemicals, acid-base break up). Implementing Safety is very important and it is necessary to follow safety procedures.
