Lab Notes:
Data & Analysis: Chemical Conductivity Electrolyte (Y/N) Ionic/ Covalent Balanced Equation NaCl 42.60 Y Ionic NaCl (s) → Na + (aq) + Cl - (aq) Na 2 CO 3 69.00 Y Ionic Na 2 CO 3 (s) → 2Na + (aq) + CO3 - (aq) NaHCO 3 33.44 Y Ionic NaHCO 3 (s) → Na + (aq) + HCO3 - (aq) KNO 3 37.23 Y Ionic KNO 3 (s) → K + (aq) + NO3 - (aq) NH 4 Cl 57.70 Y Ionic NH 4 Cl (s) → NH 4 + (aq) + Cl - (aq) NH 3 0.84 N Covalent 2NH 3 (s) → N 2 + (aq) + 3H 2 - (aq) HCl 39.29 Y Ionic HCl (aq) → H + (aq) + Cl - (aq) HCN 0.01 N Covalent HCN (aq) → H + (aq) CN - (aq) Analysis: 1. Would any of these electrolytes conduct electricity in the solid form? Explain. No, in order to conduct electricity there must be mobile charges. Charges cannot be mobile in the solid form. 2. Identify whether the compound is ionic or covalent on the data table. For a compound to be an electrolyte, what must happen when it dissolves in water? When dissolved in water the compound must ionize and have positive and negative ions. 3. After examining the chemical reactions for the electrolytes, why does
