I have 0.05g of salicyclic acid and add 100ml of 0.02MFeCl3.
I then take 0.5ml of that solution and dilute it further by adding 9.5ml of 0.02M FeCl3. What is concentration of the solution I have?
We need at least 10 more requests to produce the answer.

a) Salicylate ion + Hexaaquaiton (III) ion react to produce an ion complex, the stoichiometry is 1:1. Using this 0.05g salicyclic acid is diluted to 100 mL using 0.2M iron (III) chloride (FeCl3) solution. What is the concentration of salicyclic acid in this stock solution? b) using a pipette transfer o.5, 1, 1.5, 2 and 2.5 mL of the stock solution to five 10mL flasks and dilute to mark using 0.02M FeCl3 solution. What is the concentration of standard solutions...

2. How many ml of 10.0M HCl do I need to add to 100ml of 1.00M
NaOH to get a solution with pH = 7?
3. 75.0ml of 1.00M HCl is added to 100ml of 1.00M NaOH. what is
the pH of the resulting solution?
If I can get help with these two, I can do the others. Thank
you.

I need to make 100mL of a 50mM HCl solution. I have a 5 M stock HCl solution. How much of my 5 M HCl solution and how much water should I add to make 100mL of a 50mM HCl solution?
You have a protein solution. You take 5 ml of the solution, and add 25 ml of buffer. You then add 50 µl of the dilute protein solution to 50 µl of buffer and 2 ml of Coomassie solution. The resulting absorbance at 595 nm was 0.457. At the same time, you prepared a standard curve for the same protein using the same Coomassie assay protocol (100 µl of sample + 2 ml of coomassie reagent) The linear fit to...
