Task: Class Definition Understanding (ontology: Earth_Environment/SWEET)

Which of the following definitions best describes 'neutralization'?

A. In chemistry, the concept is a chemical reaction (also called a water forming reaction since a water molecule is formed during the process) in which an acid and a base or alkali (soluble base) react to produce salt and water (H2O). During the process, hydrogen ions H+ (a bare proton) from the acid (proton donor) or a hydronium ion H3O+ and hydroxide ions OH or oxide ions O2 from the base (proton acceptor) react together to form a water molecule H2O.

B. Any process that increases the calcium concentration of a subtance.
C. the concept is the (natural or artificial) process of formation of solid crystals precipitating from a solution, melt or more rarely deposited directly from a gas. [Wikipedia]
D. the concept is a common laboratory method of quantitative chemical analysis that is used to determine the unknown concentration of a known reactant.
