Re: Sample preparation
Actually I am bad in chemistry.
30%wt of HAuCl4 is how much of HAuCl4 dissolves in how much of HCl. And what is the concentration of the HCl?
Sorry for disturbing you

Sample preparation
Hello all,
please help me with preparing the following:
"50 μL of 30 wt % HAuCl4 in HCl solution (17 wt % Au) was added to 1.5 mL of oleylamine".
Thanks in advance

Re: Amount of solvent
Okay, So I have 0.002 mole of yttriumoxide that means I should have 0.012 mole of nitric acid, Please can you tell me how I can calculate the amount of nitric acid.

Amount of solvent
I have this balanced reaction:
Y2O3 + 6HNO3 = 2Y(NO3)3 + 3H2O
How I can determine the amount of HNO3 (solvent)?
Thanks

Re: calculating the concentration
you mean like for substance A:
c=0.008/0.04 = 0.2 M , and for substance B:
c=0.016/0.04= 0.4 M ???
c=0.008/0.04 = 0.2 M , and for substance B:
c=0.016/0.04= 0.4 M ???

Re: chemical reaction
I added Trisodium citrate and sodium hydroxide but as shape modifiers, since I am trying to prepare spherical yttrium hydroxide nanoparticles. In the end I got precipitate and I was characterized by XRD, it was what I want but I did not know the chemical reaction.
