Question

All solutions are shared between lab partners and can be re-used. You should have calculated how to make these solutions as part of your prelab assignment. Check with your partner (and TA if needed) to make sure that your calculations are correct. Make 50mL of a 2M HCI from the stock of concentrated (37%) HCI. Note the following: Once your design is cut out, place it into a large dish, and add the 2M HCI to completely submerge your ornament in the solution. While the reaction is proceeding, prepare and analyze the Cu(NO_3)_2 solution. You need to make 100mL of 100mM Cu(NO_3)_2. Note the following: Next, prepare a series of diluted solutions of copper nitrate using the serial dilution technique. You will make your solutions in your beakers or other flasks, so make sure that they are clean before you use them. In the end, you should have 5 solutions (not including the original 100mM solution)

Explanation / Answer

Initial concentration =   MV/(Vsolution + Vwater ) = 100X10/(20 = 50mM

1)    Molarirty = MV/(Vsolution + Vwater ) =50X10/(20)= 2mM

2) Molarirty = MV/(Vsolution + Vwater ) =2X10/(20)= 1mM

3) Molarirty = MV/(Vsolution + Vwater ) =1X10/(20)= 0.5mM

4) Molarirty = MV/(Vsolution + Vwater ) =0.5X10/(20)= 0.25mM
