ACID BASE BUFFERS

ACID BASE BUFFERS. Dr Nithin Kumar U Assistant Professor Biochemistry, YMC. ACIDS. Acids are substances which are:- proton donors (Lowry-Bronsted Theory) electron acceptors (Lewis Concept) dissociate to give hydrogen ions ( Arrhenius concept ) HA H + + A -

Chapter 16 Lecture 1 Buffers

Chapter 16 Lecture 1 Buffers. The Common Ion Effect Addition of a salt containing the conjugate base (acid) to a solution of a weak acid (base) decreases its ionization Example : A solution of 1.0 M HF and 1.0 M NaF HF H + + F - K a = 7.2 x 10 -4

What is the equilibrium chemical equation?

Calculate the pH of a 1.00 L solution that is 0.150 M in Benzoic acid (HC 7 H 5 O 2 ) and 0.050 M in potassium benzoate (KC 7 H 5 O 2 ). The pK a of benzoic acid is 4.20. This is a buffer solution since it contains a weak acid and its conjugate base (a salt of the acid).

Buffers and the Henderson-Hasselbalch Equation

Buffers and the Henderson-Hasselbalch Equation. -many biological processes generate or use H + - the pH of the medium would change dramatically if it were not controlled (leading to unwanted effects)
