If you are given the followingsolids:
Na3PO4Â Â Â Â Â Â Â Â Â Â Â Â Â MW= 163.94 g/mol
K3PO4                MW = 212.26 g/mol  Â
NaH2PO4Â Â Â Â Â Â Â Â Â Â MW = 119.98 g/mol
K2HPO4Â Â Â Â Â Â Â Â Â Â Â MW = 174.17 g/mol
Na2HPO4Â Â Â Â Â Â Â Â Â Â MW = 141.96 g/mol
KH2PO4Â Â Â Â Â Â Â Â Â Â Â Â MW = 136.08 g/mol
Which compounds would you use toprepare your stock solutions? Why?
I picked KH2PO4 and K2HPO4 because potassium salts dissolve morereadily in H2O which would make the lab go more smoothly. I wouldlike to know if I'm missing any valuable pieces of information inthis answer.
If you are given deionized water,the solid you selected in the previous question and the followingvolumetric glassware:
100.00 ml volumetric flask(s)
250.00 ml volumetric flask(s)
  25.00 ml volumetrictransfer pipet(s)
  10.00 ml volumetrictransfer pipet(s)
    5.00 mlvolumetric transfer pipet(s)
           Describe how you would prepare the required stock solutions (two).Your explanation should be detailed andquantitative. Â
