Weak acids do not dissociate completely in a solution. The degree of dissociation can be expressed using the acid dissociation constant (Ka) which also describes the strength of acids. The higher the value of Ka, the stronger the acid. ...
Example: If the molarity of an aqueous solution is 6.3 × 10-5 M, what is the pH? pH = −log[6.3 × 10-5] = 4.2. You can also calculate concentration from pH and pKa, the latter being derived from the acid dissociation constant **Ka**. The higher the Ka for a particular acid...
The Henderson-Hasselbalch equation gives the relationship between the pH of an acidic solution and the dissociation constant of the acid: pH = pKa + log ([A-]/[HA]), where [HA] is the concentration of the original acid and [A-] is its conjugate base. At the equivalence point, enough ...
The mol of base is added to the buffer's base, and the base's mol is subtracted from the buffer's acid. These new mols are used to find the pH. What equation is used for calculating the pH of an acid buffer? To calculate the pH of an acid buffer, the Henderson-Hasselbalch ...
Answer to: Give two important factors that determine the strength of an acid. How does an increase in each factor affect the acid strength? By...
Hsp90 is an essential molecular chaperone responsible for the folding and activation of hundreds of ‘client’ proteins, including the glucocorticoid receptor (GR). Previously, we revealed that Hsp70 and Hsp90 remodel the conformation of GR to regulate l

RIGHT TO ASSEMBLE Cells systematically use protein assembly or dissociation as cues to perform the most complex of biological functions. Therefore, the manipulation of protein-protein interactions is essential for the development of any cell controlling system. Since proteins are the workhorse...
They aim at understanding the host-virus interactions, clarifying the molecular mechanisms behind the infection. Neuraminidase assay Neuraminidase is a key viral glycoprotein involved in the virion release from infected cells. It is found on the surface of influenza viruses and cleaves sialic acid ...
