a. pH = -log(H^+)
b. pOH = -log(OH^-); then pH + pOH = pKw = 14. YOu know pOH and pKw, solve for pH.
c. See a and b above. Solve for pOH, then H^+ and OH^-
Post your work if you get stuck.
Water molecules can dissociate into hydronium ions
(H3O+ ,often just called H+ for shorthand) and hydroxide ions (OH-). The concentration of each of these ions in pure water is 10^-7. In other words, in pure water one out of every 10 million molecules is dissociated into a hydroxide ion and a hydronium ion.
A. What is the pH of a solution with a [H+]=10^ -8?
B. What is the pH of a solution with a [OH-] of 10^ -2
C. The pH of a solution is 6.5 What are the [H+] and [OH-] of the solution ?
