VOCABULARY Acid - molecule or compound which donates an H when dissolved in water, low on pH scale Aqueous - dissolved in water − Base - molecule or compound which donates an OH when dissolved in water, high on pH scale Ionic Salt - neutral compound which results from the neutralization of an acid and a base Insoluble - does not dissolve in water Oxidation Number - the charge an atom/molecule in a compound would have if it the electrons (which it shares with other molecules in the compound) were to be transferred to it completely Oxidize - to lose electrons Oxidizing Agent - molecule which helps in oxidation process and thus is itself reduced (gains electrons) Precipitate - when molecules in an aqueous solution form a solid Reduce - to gain electrons Reducing Agent - molecule which helps in reduction process and thus is itself oxidized (loses electrons) Soluble - dissolves in water Spectator Ions - ions which are involved in a chemical reaction, but do not themselves undergo chemical change ______________________________________________ REACTIONS TYPES OF REACTIONS: 1) Precipitation reaction: When two soluble ionic compounds mix to form a new insoluble ionic compound -
