Buffer capacity is a measure of a buffer solution's resistance to changes in pH as strong acid or base is added. Suppose that you have 145 mL of a buffer that is 0.320 M in both acetic acid (CH3COOH) and its conjugate base (CH3COO−) . Calculate the maximum volume of 0.180 M HCl that can be added to the buffer before its buffering capacity is lost.

What is the ph of a solution that has a hydrogen ion concentration of 1.0 * 10 -9 m?

28. which is not a reason that water is used to store spent fuel rods from nuclear power plants? water increases the speed of the chain reaction in the fuel rods. water protects nuclear power plant workers from the high temperature and radiation of the fuel rods. water acts as a radiation shield to reduce the radiation levels. water cools the spent rods. salts action
