assume that you add 1.0*10^(-5) moles of a strong acid to each of the following solutions. Determine what the final pH will be. you may assume that all of the solutions start at pH7.

A. 1 liter of pure water._______________

B. 1 liter of a solution with pH buffer at a concentration of 10^(-3) moles/liter.___________________

C. 1 liter of a solution with pH buffer at a concentration of 10^(-7) moles/liter.___________________

Solution

A. pure water have ph 7 so if we add strong acid in it the ph drop from 7 mean the water become acedic.

b. buffer solutions resist the change in ph upon adding small amount of acid or base. so in this case upon adding acid there is no significant ph change.

c.here the addition of large amount of strong acid in comparison to buffer concentration cause a drop of ph mean it become acedic.
