Asked by Cassie
a. What is the theoretical [H+] of 0.00030 M HCl? Answer: 0.00030
b. The above 0.00030 M HCl solution was prepared in the lab by dilution. The pH of the solution was measured as 4.23. Calculate the [H+] from the measured pH.
Answer: pH = 4.23
= 10^ (-4.23)
= 5.88 x 10^-5
c. Calculate the percent error in the measured [H+].
Answer:
(0.00030-(5.88x10^-5))
---------------------- x 100
(0.00030)
= 80%
Am I on the right track?
