A Tris buffer at pH 6.0 (here "Tris" is a nickname use for Tris hydroxymethyl amino methane). For the given pKA table is Tris a compound you would select for a buffer at pH 6.0?
Provided the compound for this buffer, determine the equilibrium concentrations you'd suppose for the conjugate acid and conjugate base species into the buffer at pH 6.0. Suppose that you are dealing along with 1.00 liters of buffer at a complete buffer concentration of 10.0 mM.
Ans:
[A-] + [HA] = 0.010 M
1.44668[HA] = 0.010 M
[HA] = [H2CO3] = 6.9X 10-3M and [A-] = [HCO3-] = 3.1 X 10-3M
1.8128[HA] = 0.010
[HA] = [HMES] = 5.5 Mm
[A-] = [MES-] = 4.5mM
which is the main postulate of bohr''s model of atom
Hexagonal Close Packed (HCP) Structure:- The cell of HCP system has 12 corner atoms, one at each corner of the hexagon with two base centered atoms, one at the top face of the
Q. Show the Colorimetric analysis? Colorimetric analysis depends on the variation of the colour with the change in concentration of the compound. Usually, absorption of light i
plz explain me about buffer capacity and its type
Alkyl ligands form metal carbon σ bonds. Usually they occur in conjunction with other organic ligands or CO, but may be achieved on their own, as in tungsten hexamethyl (1), and
