Which is stronger acid HA or HB?
In this example, HA is the stronger acid because its proton can fall to a lower potential energy when it joins with B– to form HB.
What is ha in buffer equation?
In its general form, the Henderson–Hasselbalch equation is a useful expression for buffer calculations. It can be derived from the equilibrium constant expression for a dissociation reaction of the general weak acid (HA) in Equation (1.3): (1.4) where K is the equilibrium constant at a given temperature.
How do you find ha in chemistry?
The Henderson-Hasselbalch equation is as follows: pH = pKa + log ([A-]/[HA]), where “pKa” is the dissociation constant, a number unique to each acid, “[A-]” represents the concentration of conjugate base in moles per liter (M) and “[HA]” represents the concentration of the acid itself.
Which is a And ha?
In this chemical equation, the molecule HA is the general formula for an acid. “A” is just a placeholder—it could be a picture of a banana for all we care. An example of an acid written in shorthand is HCl (hydrochloric acid), where a chlorine atom gets plopped where the “A” (or the banana) used to be.
How do I calculate ka?
Dissociation Constant for Acetic Acid Since x = [H3O+] and you know the pH of the solution, you can write x = 10-2.4. It is now possible to find a numerical value for Ka. Ka = (10-2.4)2 /(0.9 – 10-2.4) = 1.8 x 10-5.
What is pH buffer solution?
A buffer solution (more precisely, pH buffer or hydrogen ion buffer) is an aqueous solution consisting of a mixture of a weak acid and its conjugate base, or vice versa. Buffer solutions are used as a means of keeping pH at a nearly constant value in a wide variety of chemical applications.
How does the chemistry of myoglobin and Hb-O 2 work?
The Chemistry of Hemoglobin and Myoglobin. Once the Hb-O 2 complex reaches the tissue that consumes oxygen, the O 2 molecules are transferred to another protein myoglobin (Mb) which transports oxygen through the muscle tissue.
What is the structure of the haemoglobin molecule?
Haemoglobin Structure 1 𝜶 subunit – It is made up of alpha polypeptide chain having 141 amino acid residues. 2 𝝱 subunit – It is made up of beta polypeptide chain having 146 amino acid residues. 3 Heme group – It is an iron-containing prosthetic group, which is attached to each polypeptide chain. It contains iron in… More …
What kind of atom is at the center of heme?
At the center of the heme is an Fe(II) atom. Four of the six coordination sites around this atom are occupied by nitrogen atoms from a planar porphyrin ring.
