You have 855 ml of a solution that is composed of 15.2 grams of NH3 and 22.2 grams of Aluminum Chloride mixed well. kb for ammonia = 1.8 E -5.
a. is this a buffer solution? why or why not?
b. if it is a buffer solution what is the pH of this buffer solution?
c. how many mil of 1.5 M HCl can be added to this solution before the buffer is exhausted?
d. how many ml of 1.5 M NaOH can be added to this solution before the buffer is exhausted?
We add excess Na2CrO4 solution to 17.0 mL of a solution of silver nitrate (AgNO3) to form insoluble solid Ag2CrO4. When it has been dried and weighed, the mass of Ag2CrO4 is found to be 0.310 grams.

Deuterium oxide (D20, where D is deuterium, the hydrogen-2 isotope) has an ion-product constant, kw1 of 8.9 x 10^-16 at 20 degrees Celsius. Calculate [D+] and [OD-] for pure (neutral) D20 at this temperature.
When filling a cuvette with distilled water and measuring it with a spectrofluorometer, upon excitation at 350nm, a band around 397nm appears. This is either a fluorescence band or a Raman band. Suggest what you can do experimentally to identify w..
Consider the equation A(aq) + 2B(aq) -> 3C(aq) + 2D(aq). In one experiment, 45.0 mL of 0.050 M A is mixed with 25.0 mL 0.100 M B. At equilibrium the concentration of C is 0.0410 M. Calculate K.
