Week 10 – Experiment 7 : REACTION PROPORTIONS

Completing the Graphs:

Graph 1

Using the graphing software built into MicroLab, you should plot a

graph of “g of Product” versus “mL of Ni Salt” – print a copy for each

lab partner.

Graph 2

Calculate the “mole ratio” of Ni/DMG for each experiment (1-5) then

plot a second graph of “g of Product” versus “Ni/DMG Mole Ratio” –

print a copy for each lab partner.

This graph will then allow you to complete the calculations needed

for the Data Report Sheet.

Instructions for using the graphing software are available on

the 1515L page related to this experiment.

Week 10 – GAS LAWS

Ideal Gas Law: PV = nRT

Charles’ Law: Volume ∝∝∝∝ Temperature

so: V1T1 = V2T2

Boyle’s Law: Pressure ∝∝∝∝ Volume

so: P1V1 = P2V2

Week 10 – BOYLE’S LAW

MicroLab analysis unit has a built-in pressure sensor; attaching a graduated

syringe enables the measurement of volume-pressure changes

Week 10 – BOYLE’S LAW

Setting up the interface appropriately to investigate Boyle’s Law
