Sulfuric acid
Sulfuric acid

Sulfuric acid, (British English: sulphuric ,acid,), H 2 S O 4, is a strong mineral ,acid,. It is soluble in water at all concentrations. It was once known as oil of vitriol, coined by the 8th-century Alchemist Jabir ibn Hayyan, the chemical's probable discoverer. ,Sulfuric acid, has many applications, and is produced in greater amounts than any other chemical besides water.

Titration - Wikipedia

Titration, (also known as titrimetry 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, is prepared as a standard solution of known concentration and volume. The titrant reacts with a solution of analyte (which may also be termed ...
