Problem- Why do firefighters recommend the use of a deluging volume of water when extinguishing an oxidizer-supported fire? What may happen to a large (i.e., 30-50lb) container of trichloro-s-triazinetrione, or calcium hypochlorite, if it is left to sit in the water and muck remaining in a building after firefighting efforts have ended, but clean-up will not begin for several days? The assumption here is that the plastic container has been compromised in some way by the heat of the fire and possibly creating cracks in the base or sides.
This is not a problem given in the book, so I just need the full solution of deriving!
You need to prepare 100.0 mL of a pH=4.00 buffer solution using 0.100 M benzoic acid (pKa = 4.20) and 0.200 M sodium benzoate. How much of each solution should be mixed to prepare this buffer
A paint mixture containing 25.0 wt% of a pigment and the balance water sells for $18.00/kg, and a mixture containing 12.0 wt% pigment sells for $10.00/kg. If a paint retailer produces a blend containing 17.0 wt% pigment, for how much ($/kg) should..
