Part C What is the conjugate acid of HPO42- ? Express your answer as a chemical formula. View Available Hint(s) Submit Previous Answers Request Answer According to the Brønsted-Lowry theory, an acid is any substance (molecule or ion) that can transfer a proton (H" ion) to another substance, and a base is any substance that can accept a proton. Acid-base reactions are proton-transfer reactions, as follows: + HA + acid B base = BH acid A. base Chemical species whose...
a buffer is a solution that has a Weak acid in equlibirum with its conjugate base. So can a buffer solution has a weak base in equlibirum with its conjugate acid? So basically, to create a buffer, you can mix a weak acid with its conj. base OR a weak acid + strong base OR a weak base with a strong acid? Am i Correct?

Ammonia, NH3, is a weak base because a proton can readily bind to the lone pair on the nitrogen to produce the ammonium ion, NH4+. Organic compounds that contain nitrogen are also weak bases for the same reason. Amines are compounds derived from ammonia in which one or more of the hydrogens are replaced by a carbon-containing group (R). The simplest amine is methylamine in which is a "methyl" group, CH3. Its kb is 4.4 X 10-4. Write the balanced...
