how can i get the initial concentration of thiosulfate ion
(S2O3) in reaction mixture 1 ?
and also how can i determine the initial reaction rate for
mixture 1?

Rates of Chemical Reaction Lab
Iodination of Acetone
1- a student made up a reaction mixture
consisting of 10 mL 4 M acetone, 5 mL 1.0 M HCl 10 mL 0.005 M
I2 and 25 mL H2O.
Why is the concentration of iodine so much lower than the other
reactants?
3. How are time and rate related? How are 1/time and
rate related?
4. What does it mean when someone says a reaction is “first
order”?
5. In a...

You need to prepare 10.0 mL of diluted Cuso, solutions with the concentrations listed for Trials 1 through 4 in the table below. Before coming to lab, determine what volumes of 0.040 M CuSO, stock solution and H,O need to be mixed together. Fill in the table with the volumes you determined. Trial Number 0.040 M CuSO4 (ml) H2O (mL) Diluted Concentration (M) 0.0050 0.010 0.020 0.030 0.040 stock solution
Find each values of CuSO4 and H2O
You need to prepare 10.0 mL of diluted CuSO4 solutions with the concentrations listed for Trials 1 through 4 in the table below. Before coming to lab, determine what volumes of 0.040 M CuSO4 stock solution and H2O need to be mixed together. Fill in the table with the volumes you determined. Trial Number 0.040 M Cuso (mL) HO (mL) Diluted Concentration (M) 0.0050 0.010 0.020 0.030 0.040 stock solution
How do you find the initial concentration if you are only
given the initial volume and final volume? I have tried using the
V(i) x C(i) =V(f) x C(f) equation but it needs at least 3 figures
so I'm a bit lost right now.
