Title: 07 JUN 2004: Buffers
Post by: Donaldson Tan on June 07, 2004, 12:05:33 PM

Would a buffer made from HF &NaF be suitable for maintaining ammonia predominantly as NH₃ and not NH₄^-, and ethanoic acid as CH₃COOH & not CH₃COO^-? Please Explain

What do you precisely mean under word - predominantly - 90%, 95%, 99% or more.
