Homework Help: chemistry

Posted by Smiley on Sunday, August 19, 2007 at 4:29am.

Again, from my previous question about gravimetric analysis...
Why can't NH4Cl be used as a substitute for NH3 in precipitating MgNH4PO4*6H2O?
Please critique my thought:
I found out that a precipitate is more soluble at lower pH and since NH4Cl acidic, it will cause the precipitate to revert to its dispersed state and may cause loss of analyte. Am I right?

Yes.

thanks a lot :D
