3. Give the letters of the solutions below that represent buffers. (a) a solution of sodium hydrogen carbonate and sodium chloride; (b) a solution of acetic acid and sodium acetate; (c) a solution of sodium hydrogen sulfate and sodium sulfate; (d) a solution of aniline and anilinium nitrate
Homework Answers
Buffer is the system which is made by the presense of a weak acisd and its conjugate base in the solution.
(B) solution of acetic acid and sodium acetate because acetic acid is a weak acid and sodium acetate is its conjugate base
(C) solution of sodium hydrogen sulfate and sodium sulfate here sodium hydrogen sulfate is weak acid and sodium sulfate is a conjugate base.
