Sodium Hydroxide Specific Heat Capacity

Specific heat for some common liquids and fluids - acetone, oil, paraffin, water and many more

Heat of Solution Purpose To calculate the heat of solution for sodium hydroxide (NaOH) and ammonium nitrate (NH 4NO 3) Background For a given solute, the heat of solution is the change in enerrgy that occurs as one mole of the solute dissolves in water. During the dissolving process, solutes either absorb or release energy. The heat capacity of the calorimeter, C cal, is determined in Part I of the procedure. Also, it is assumed that the specific heat capacity of the solution, spheat, is approximately equal to that of water (spheat water = 4.184 J/g×°C). The moles of water produced in the. To a calorimeter containing 300 g of water at 20.00 oC, 10.65 g of NaOH, also at 20.00 oC was added. The temperature change, which was monitored by a digital probe with negligible heat capacity. Sodium hydroxide NaOH or HNaO CID 14798 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities. The number of moles of sodium hydroxide present. NaOH = 40 g/mol NaOH (s) + H2O (l) 2 g× 1 mol 40 g = 0.05 mol NaOH NaOH (s) + HCl (aq) 2 g× 1 mol 40 g = 0.05 mol NaOH NaOH (aq) + HCl (aq) 0.1 L× 0.5 mol 1 L = 0.05 mol NaOH d. The amount of heat evolved per mole of sodium hydroxide used. This value should be reported in kJ/mol and is the.

Heating Energy

The energy required to heat a product can be calculated as

q = c_p m dt (1)

where

q = heat required (kJ)

c_p = specific heat (kJ/kg K, kJ/kg ^oC)

dt = temperature difference (K, ^oC)

Example - Required Heat to increase Temperature i Water

10 kg of water is heated from 20 ^oC to 100 ^oC - a temperature difference 80 ^oC (K). The heat required can be calculated as

q = (4.19 kJ/kg K) (10 kg) (80 ^oC)

= 3352 kJ
