S: (n) double replacement reaction (a chemical reaction between two compounds where the positive ion of one compound is exchanged with the positive ion of another compound)
S: (n) chemical reaction, reaction ((chemistry) a process in which one or more substances are changed into others) "there was a chemical reaction of the lime with the ground water"
S: (n) displacement, displacement reaction ((chemistry) a reaction in which an elementary substance displaces and sets free a constituent element from a compound)
S: (n) hydrolysis (a chemical reaction in which water reacts with a compound to produce other compounds; involves the splitting of a bond and the addition of the hydrogen cation and the hydroxide anion from the water)
S: (n) oxidation, oxidization, oxidisation (the process of oxidizing; the addition of oxygen to a compound with a loss of electrons; always occurs accompanied by reduction)
S: (n) reduction, reducing (any process in which electrons are added to an atom or ion (as by removing oxygen or adding hydrogen); always occurs accompanied by oxidation of the reducing agent)
S: (n) saponification (a chemical reaction in which an ester is heated with an alkali (especially the alkaline hydrolysis of a fat or oil to make soap))
