Presentation transcript:

Covalent compounds: will not dissociate → d.f. = 1 Dissociation Factor Dissociation factor: How many particles the solute will break into in solution Dissociation Factor Covalent compounds: will not dissociate → d.f. = 1 Ionic compounds: will dissociate into ions → d.f. = # of ions per molecule

Dissociation Factor Examples What is the dissociation factor for each compound? 1. Determine if the compound is ionic or covalent 2. CIRCLE any polyatomic ions 3. Determine the dissociation factor AlPO4 N2O4 CaI2 PCl5 Pb(OH)4 XeF4 Cu2CO3

Dissociation Factor Practice What is the dissociation factor for each compound? 1. Determine if it is ionic or covalent 2. CIRCLE any polyatomic ions 3. Determine the dissociation factor 1. NH4Cl 2. CO2 3. Ca3(PO4)2 4. CaCl2 5. Fe(NO3)2 6. NaOH 7. NaCl 8. Li2SO4 9. Mg3P2 10. CaC2O4
