The equilibrium constant for the reaction AgBr(s) Ag +(aq) + Br – (aq) is the solubility product constant, K sp = 7.7 × 10 –13 at 25°C. Calculate ΔG for the reaction when [Ag +] = 1.0 × 10 –2 M and [Br –] = 1.0 × 10 –3 M. Is the reaction spontaneous or nonspontaneous at these concentrations?

Abeaker with 2.00×102 ml of an acetic acid buffer with a ph of 5.000 is sitting on a benchtop. the total molarity of acid and conjugate base in this buffer is 0.100 m. a student adds 4.70 ml of a 0.360 m hcl solution to the beaker. how much will the ph change? the pka of acetic acid is 4.740.
