Pluchino – Regents Chemistry Atoms, Formuals & Reactions – 07 Predicting Products Aim: How can we predict the products of a double replacement reaction? Do Now: Na 2 CO 3 (aq) + AgNO 3 (aq) ? Ionic Compounds: formed when a cation and an anion are electrostatically attracted to one another When dissolved in water, ionic compounds will dissociate (break apart) into their ions. Use the subscript of the cation to determine the charge of the anion and vice versa. Mn 2 O 7 (s) 2Mn 7+ (aq) + 7O 2- (aq) Practice: Write the dissociation equation for each of the following ionic salts. 1. Al 2 S 3 (s) 2. K 2 O (s) 3. Cu 2 SO 4 (s) If an ionic compound has more than two elements in it, a polyatomic ion must be present… Do NOT change the formula of a polyatomic! Use Table E for a list of polyatomic ions
