Hydrogen Tartrate Wang Haina 1. Aim 1. To determine the solubility of potassium hydrogen tartrate (KHT) at various temperatures from 10°C to 50 °C‚ and determine the corresponding Ksp at these temperatures. 2. To obtain the changes in enthalpy and entropy of the dissolution of KHT from the dependence of Ksp on temperature. 2. Results and discussion 2.1 Collection of data A portion of KHT (1 to 1.5 g) was added into about 100 mL of deionised water to prepare a saturated KHT solution

CHG 3111 Unit Operation Gas-Liquid Separation Text Book: Chapter 10 Separation Processes Introduction: Many chemical and biological processes occur as a mixtures of different phases‚ gas‚ liquid and solid. To separate or remove one or more of the components from its original mixture‚ it must be contacted with another phase. The two phase pair can be gas-liquid‚ liquid-liquid or liquid-solid. When different phases are brought into contact‚ a solute or solutes can diffuse from on phase to the

how long it takes for the colour change to occur in different temperatures determined by the use of an electric water bath. With these results‚ the effect of temperature on the rate of reaction will be investigated. 2. Determine the activation enthalpy with and without the catalyst ammonium molybdate(VI) and with different protic acids and use this to compare the effectiveness. To find out which catalyst is most effective‚ this aim will be carried out as an iodine clock reaction. The goal
