       Calculating Ph in (NH4)[sub]2[/sub]S  Bookmark   

I would like to ask some not directly drug related questions, but since this is the place where people that know much about chemistry seem to gather maybee you could help me..tongue

1.How should I estimate and calculate pH in 0.01 M (NH4)2S

2. What hybridisation does the carbon atom have in CO, CO2 and CO32-

3. Please help me to write a formula for disolving PbSO4 in alkali. I suggest PbSO4(s) + 2OH- + H2O -----> Pb(OH)3-+ HSO4-

Thanx for any help

As this is obviously your homework, you should perhaps consult the index in your textbook and google first?
