Liquid unknown CONCLUSIONS 1. 2. 3. 4. 6. 7. 8. 9. 10. EXPERIMENT 2 POST-LABORATORY QUESTIONS Is p-toluidine a solid or liquid at room temperature? What solvent would you use to measure the density of cadmium nitrate? Convert your densities to kg/L and compare these values with those in g/mL... If air bubbles were trapped in your solid beneath the liquid level in your density determination, what error would result in the volume measurement, and what would be the effect of this error on the calculated density? A liquid unknown was found to be insoluble in water and soluble in cyclohexane and alcohol; the unknown was found to have a boiling point of 145 °C at 658 mm Hg. What is the substance? What could you do to confirm your answer? A liquid has a density of 2.46 + 0.01 g/mL and is insoluble in cyclohexane. What is the liquid? What is the boiling point of cyclohexane at 600 mm Hg? What will be the boiling point of ethanol at 690 mm Hg when its normal boiling point at 760 mm Hg is known to be 78.3 degrees C? What is the color of MnSO4? What is its solubility in cold water? What are the formula, molecular weight, and color of potassium permanganate? (* For questions 9 and 10, Please consult the Chemistry Handbook. *)
