The relationship between hydrogen ion concentration and pH is inverse As pH is a logarithmic function, there must be a 10-fold change in [H+] for each unit change in pH pH 8.0 – [H+] = 10 nmol/l pH 7.0 – [H+] = 100 nmol/l pH 6.0 – [H+] = 1000 nmol/l...
A measure of the acidity of the acidity or alkalinity of a solution It is calculated by taking the negative logarithm to the base 10 of the H+ concentration in solution It is dimensionless and has no...
The ability of an ion or molecule to act as either an acid or base depending upon the reaction conditions The most commonly encountered amphoteric molecule is water which is able to either donate or accept a...
The concept of conjugate acids and bases arise from the Bronsted-Lowry acid-base theory When an acid (HA) dissociates into its ions in a solvent it loses a hydrogen ion (H+) The species that is formed is the “conjugate” base of the acid (A-) – it is...
Defined by the International Union of Pure and Applied Chemistry (IUPAC) as: Acid A molecular entity or chemical species capable of donating a hydron (proton) or capable of forming a covalent bond with an electron pairA Base A molecular entity or chemical species...
