hello i was trying to make a PBS as usual and the component of it as following to make 500 ml of it:
-Na2HPO4 0.575 g -NaCl 4g -KH2PO4 0.1 g -KCl 0.1 g -CaCl2-2H2O 0.065g -MgCl2 0.0235 normally we dissolve Na2HPO4 first and we add the remaining components. we check the pH which was around 6.8 and we added 10 M of NaOH however, we observed formation of cloudy precipitate. can someone explain why this formation of white precipitate? _______________________________________________ Methods mailing list [email protected] http://www.bio.net/biomail/listinfo/methods
