a)
What is [OH-] in an aqueous solution (in molL-1) containing
[H3O+] = 9.03 x 10-6 molL-1?
Remember: if you want to express an answer in scientificnotation, use the letter "E". For example "4.32 x 104"should be entered as "4.32E4".
b)
What the pOH of a solution containing[H3O+] = 2.63 x 10-11 molL-1 ?
Report your answer to at least 1 decimal place.
c)
Consider a weak acid "HA". What is the pH of a 0.236 molL-1 solution of HA?
The KA of HA is 2.15 x10-5 .
Report your answer to at least 1 decimal place.
d)
Consider a weak acid "HA". What is the percent ionization of a0.306 mol L-1 solution of HA? Just enter thepercentage as a number and do not include the "%" sign. Report youranswer to at least 1 decimal place.
The KA of HA is 2.88 x10-6 .
For partial credit, enter the equilibrium[H3O+] (in M) instead.
