The Ksp for silver sulfate (Ag2SO4) is 1.2 multiplied by 10-5. Calculate the solubility of silver sulfate in each of the following.
(a) water
(b) 0.29 M AgNO3
(c) 0.39 M K2SO4
A 100. mL sample of 0.200 M aqueous hydrochloric acid is added to 100. mL of 0.200 M aqueous ammonia in a calorimeter whose heat capacity (excluding any water) is 480. J/K. The following reaction occurs when the two solutions are mixed.
