Presentation Transcript

  1. LIME Tuba Naz BOZKURT 213 9/A

  2. Calcium oxide (quicklime) • Calcium hydroxide (slaked lime)

  3. Quicklime •  It is a white, caustic, alkalinecrystalline solid at room temperature. • It releases heat when dissolved in water. • It’s a base. • Its chemical formula is CaO.

  4. Melting point :2572 °C • Boiling point :2850 °C • Solubilityin acids :soluble • Solubilityin methanol :insoluble • Acidity :12.8

  5. SlakedLime • It is a colorless crystal or white powder. •  It is of low toxicity • Calcium hydroxide is used in many applications, including food preparation.

  6. Meltingpoint: 580 °C • Solubility in water :0.189 g/100 mL (0 °C) • Solubility :Solublein glycerolandacids.Insoluble in alcohol. • Acidity:12.4 • Basicity:(pKb)2.37

  7. Heat of Solution of Calcium Hydroxide • Aim: Determine the molar enthalpy of solution of calciumhydroxide.

  8. Approach: • Determine the molar enthalpy of neutralization using the Heat of Neutralization experiment. • Using calorimetry, determine the molar enthalpy of solution by dissolving calcium hydroxide in an aqueous HCl solution and accounting for the heat of neutralization in the calculations.
