Acid rain over the Great Lakes has a pH of about 4.5. Acid rain over of the West Coast has a pH of 5.3. How many times more concentrated is the acid in rain over the Great Lakes?
Suggest a reason why the equilibrium between succinic acid and acetic anhydride lies on the side favoring formation
What is the minimum uncertainty in the position of a hydrogen atom in a particle accelerator given that its speed
Calculate the pH of a solution that is 0.25M pyridine, C5H5N and 0.75M in pyridinium bromide, C5NHBr. (Kb for C5H5N= 1.7 * 10^-9)
The generic metal hydroxide M(OH)2 has Ksp= 6.64x10^-18. (Note: In this particular problem, because of the magnitude of the Ksp and the stoichiometry of the compound, the contribution of OH from water can be ignored. However, this may not always b..
