... % of Nickel in NISO . 6H O = 58.7 / 262.8 x 100 =22.3% Figure 1.1 Figure 1.2 Procedure: * The next stage of the experiment was the practical procedure stage (as shown in figure 1.3), which was carried out in the following manner: 1. I carefully weighed out 2.6g of hydrated nickel sulphate using a weighing bottle 2. Next I added the nickel salt to a 100cm beaker and added 25cm of deionised water, and then reweighed the bottle to determine if any weight should be deducted for calculation purposes (a negligible weight was left in the bottle). 3. Next I stirred the solution until the solid was fully dissolved, then transferred the solution to a 100cm standard flask. 4. For the next step in the procedure I rinsed the beaker with deionised water, and repeated several times until the solution was nearly at the graduation mark, then using a dropper I made it up to the graduation ...
