Fsperimental
You will be provided with a solution of 2,0 moldm" Cuso4
using your pipette and volumetric flasks, dilute the solution to give
solution 1.0,0.5,0.02 and 0.01 moldm-3 strength. Pipette 10 cm3 of each dilution into test-tube and show this to your laboratory instructor.
* Preparation of Standard Solutions:
You will be provided with small quantity of sodium chloride or any
other sali with known molecular mass. You are required to calculate and
prepare 250 cm' of 0.01 moldm'of this salt using your volumetric flask.
Show all the calculations and record all weighing in your data book.
