Standard partial molar heat capacities for the three salts and the standard partial molar volume of NaOH(aq)have been derived at 25 ☌. In particular, it has been confirmed that the heat Capacity data for Na2CO3(aq) at low concentrations must be corrected for the hydrolysis of the carbonate ion. A number of inadequacies in previous models at high concentrations and for extrapolation to infinite dilution are discussed. The heat capacities for Na2SO4(aq), Na2CO3(aq), and NaOH(aq) and literature data for the apparent molar volumes of NaOH(aq) at 25 ☌ were correlated using the Pitzer formalism. On the basis of these measurements, an experimental protocol suitable for the reliable determination of the heat capacities of concentrated electrolyte solutions by Picker calorimetry was established. Caustic soda lye is a solution of sodium hydroxide (NaOH) in. The calorimeter performance was checked using concentrated NaCl(aq) solutions. Specific heat for some common liquids and fluids - acetone, oil, paraffin, water and many more The number of moles of sodium hydroxide present. If water has a specific heat capacity of 4200 J/ (Kg.degK), the specific heat. 2049 Sodium disilicate, crystalline, specific heat, at low temperatures. You will find that the specific heat capacity of the sodium hydroxide in pure form is about 1491.5 J/ (Kg.degK). kg-1) have been measured at 25 ☌ with a Picker flow calorimeter. Item Sodium carbonate - sodium sulfate - sodium hydroxide - water system.
