Chapter 16 - Reaction Types

precipitation reactions

2 aqueous compounds react and form a solid precipitate

acid-base reactions

H+ ion is transferred between reactants

redox reactions

oxidation number of 2 elements change over the course of a reaction

strong acid

an acid that reacts fully, often halogens

weak acid

an acid that only partially reacts, typically organic

reduced

an e^- is gained and the oxidation number decreases

oxidized

an e^- is lost and the oxidation number increases

strong base

a base that fully reacts

weak base

a base that only partially reacts

general acid reaction formula

H-A (aq) + H₂O (L) → A^- (aq) + H₃O⁺ (aq)

A = acid

general base reaction formula

B-OH (aq) → B⁺ (aq) + OH^- (aq)

B = base

general acid-base reaction

H-A (aq) + B-OH (aq) → A-B (aq) + H₂O (L)

A = acid

B = base

precipitation reaction general equation

AB (aq) + XY (aq) → AX (aq) + BY (s)
