Oil of Wintergreen is 98% (6.4 M) methyl 2-hydroxybenzoate (CH803 see below). Calculate the pH of a solution of Wintergreen Oil if the Ka = 10-9.72 (pKa = 9.72).

Caustic soda or "lye" is Sodium Hydroxide. Calculate the pH of a 6 M NaOH solution.


Oil of vitriol is Sulfuric Acid. Calculate the pH of 8M H2SO4. The first dissociated proton is strongly acidic; the second is significantly weaker.
