CHEM 1331 REVIEW CHAPTER 4 Ionic Reactions : Ionic compounds + water sometimes dissolve (soluble). If soluble, they dissociate into ions – ELECTROLYTES TABLE 4-1 Some covalent compounds + water dissolve and dissociate – ACIDS (contain H + ) and BASES (contain or produce OH - ) If complete dissociation – STRONG – Table on p. 143 – KNOW IT If partial dissociation - WEAK Covalent compounds in water sometimes dissolve and DON’T DISSOCIATE ( NON- ELECTROLYTES ) Combination of Soluble Ionic Compounds can react via double displacement: cation(1)anion(1) + cation(2)anion(2) cation(1)anion(2) + cation(2)anion(1) 4 things can happen (express by using NET IONIC EQUATIONS, eliminate SPECTATOR IONS which are ions that stay in solution): a) Nothing (both products soluble) b) Precipiate (one product not soluble) [Cation + Anion CationAnion(s)] c) Neutralization (one cation is H + , one anion is OH - ) [H + + OH - H 2 O] Acid + Base Water + “Salt” d) Gas formed CO 3 2- + 2 H
