- Which is the buffer region in the titration curve below?arrow_forward3) Ammonia, NH3, is toxic to a wide range of aquatic organisms including snails, insects, and fish. The ammonium ion, NH4", is much less toxic since the cation does not diffuse rapidly across cell membranes. The US EPA limit for total ammonia in natural waters is 1.9 mg/L at pH 7. a. What is this limit in molar units? b. What is the concentration of NH3 at pH 7? c. What is the concentration of NH3 at pH 6? d.
