  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.

  1. Determining the concentration of lime water

    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).

  2. Determine the 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.

  1. Chemistry concentration of lime water.

    An accurate way of doing this is to use a volumetric flask and pipette. I want to dilute the acid to 0.1 moles, so I pipette 25.0cm3 of HCl from the original bottle and place it in the 500cm3 volumetric flask.

  2. Chemistry concentration of lime water.

    Add a few drops of methyl orange indicator. 4) Wash the burette with some of the acidic solution being used. Maker sure the solution runs into the tip of the burette. 5) Once washed fill the burette up to the meniscus point at 0 point, this should be read at eye level.
