weighed watch glass and record the mass of the product. Write a balanced equation for the synthesis and hence calculate the percentage yield (based on the mass of the nickel(II) chloride hexahydrate used) and record it, with working, in the lab notebook. 5.0 EXPERIMENTAL PROCEDURES I. Wear gloves throughout the experiment, and work in a fume cupboard throughout. Using an appropriate balance for synthetic work, weigh out 1.5 g of nickel(II) chloride hexahydrate and record the mass used. 2. Dissolve...
