What determines the pH of a solution?
In chemistry, pH ( / piːˈeɪtʃ / pee-AYCH ), also referred to as acidity or basicity, historically denotes " potential of hydrogen " (or "power of hydrogen"). [1] . It is a logarithmic scale used to specify the acidity or basicity of aqueous solutions.
In organic chemistry, the phenyl group, or phenyl ring, is a cyclic group of atoms with the formula C 6 H 5, and is often represented by the symbol Ph (archaically φ). The phenyl group is closely related to benzene and can be viewed as a benzene ring, minus a hydrogen, which may be replaced by some other element or compound to serve ...
The isoelectric point (pI, pH(I), IEP), is the pH at which a molecule carries no net electrical charge or is electrically neutral in the statistical mean. The standard nomenclature to represent the isoelectric point is pH(I). However, pI is also used. For brevity
The pH value of a neutral solution is 7.0 at 25 C (standard laboratory conditions). Solutions with a pH value below 7.0 are considered acidic and solutions with pH value above 7.0 are basic.
In electrochemistry, the standard hydrogen electrode (abbreviated SHE ), is a redox electrode which forms the basis of the thermodynamic scale of oxidation-reduction potentials.
Acid value. In chemistry, acid value ( AV, acid number, neutralization number or acidity) is a number used to quantify the acidity of a given chemical substance. It is the quantity of base (usually potassium hydroxide (KOH)), expressed as milligrams of KOH required to neutralize the acidic constituents in 1 gram of a sample.
Titration (also known as titrimetry [1] and volumetric analysis) is a common laboratory method of quantitative chemical analysis to determine the concentration of an identified analyte (a substance to be analyzed). A reagent, termed the titrant or titrator, [2] is prepared as a standard solution of known concentration and volume.
