Question
The acidity of a solution is measured by its pH.
If H
represents the concentration of hydrogen ions (in moles/liter) in the solution, the pH is defined by
pH:
- log H+
Suppose a solution has pH = 1.09.
(a) Rewrite the logarithmic form of the equation into exponential form. (O indicates two way equivalence)

(b) Find
H+, the approximate concentration of hydrogen ions. (Select one)
O [H*]~0.9174 moles/liter
[H*]~ -0.0374 moles/liter
[H*]=
= 26.719 moles/liter
[H']~0.0374 moles/liter
[H]= -12.3027 moles/liter
O [H*]~ 0.08128 moles/liter
O [H*]= 0.04064 moles/liter
