im having difficulty solving!
The data used here are for illustrative purposes. The data you obtain will be different. Note: The data u C DETERMINATION OF COPPER Preparation of a Stock Cu2+ Solution ord the mass of copper wire used. Use this datum in conjunction with volume of the volumetric flask to determine the concentration of Cul in the stock solution. Express this concentration as mg Cu/mL solution. EXAMPLE: The mass of copper wire is 0.236 g (236 mg): the...

I really just need all the equations, please and thank you.
MATERIALS: cene nitric acid, HNO, 3.0M sodium hydroxide, NaOH 6.0 M sulfuric acid, H2SO4 zine metal DI water PROCEDURE: Make sure you record detailed observations after almost every step. You will also need to write the balanced chemical equations for almost every step. Make sure you answer any questions associated with a step 1. Weigh approximately 0.5 g of copper metal and record the weight. Place the copper in...

How do I calculate the concentrations for my data sheet lab. I
have not started my lab yet but I just need to see how i would
calculate it with absorbance. Do i just use Beer's law or is there
any other method of solving the concentrations.

What I have so far for data etc.
My question I need help with though is:
This is my data and what I have so far but this is the
question I actually need help with:
-What ions are present in the titrated solution after the
beginning of the titration but before the equivalence point? How
about after the equivalence point when the conductivity is rising?
Lastly, compare your results from 2 and 4 above with the actual
molarity of...
