[quote=4everluv]  awwhh, my chem. lab questions are so hard..!!!
-why is acetic acid added before testing for lead with chromate ion in qualitative analysis?
-what are the specific solubilities of PbCl2(lead chloride) and AgCl (silver chloride) in ice-cold water (in g/100g H2O) ????????????????????????? why couldnt I find them online?!   [/quote]
:041:

Currently I only can solve the second one for you.  


(1) http://en.wikipedia.org/wiki/Solubility_table (This link is one the Wikipidia, and it contain the different value of solibilities)  

(2) http://en.wikipedia.org/wiki/Lead%28II%29_chloride  ( this link is about the lead chloride)

(3) http://en.wikipedia.org/wiki/Silver_chloride    ( this link is about the silver chloride)

(4) http://bilbo.chm.uri.edu/CHM112/tables/KspTable.htm ( this link is about the solibility of different salt in 25 oC, I hope this could help you also)

(based on the data, the solibility of PbCl2 in icecold water would be 0.67g/ 100g water )
(based on the data, AgCl Solubility 52 x 10-6g/100g water at 50°C ) :028:
