Sodium Hydroxide Specific Heat Capacity

  

Equal volumes, 50.0 mL, of 3.0 M hydrochloric acid and 3.0 M sodium hydroxide solutions having an initial temperature of 20.0°C react in a calorimeter. The resultant solution records a temperature of 40.0°C. The heat gained by the resultant solution can be calculated using. Sodium hydroxide, also known as lye. Heat capacity (C) 59.5 J/mol K Std molar entropy (S o 298). Specific foods processed with sodium hydroxide include.

The DOW reference is good because they make Sodium Hydroxide. A good library reference on chemicals is Perry's Handbook of Chemical Engineering. It has a table of Sodium Hydroxide heat capacities for solutions. And NO, the density of a solution is NOT the same as water unless it is very dilute. Swampie777 ( Chemical Engineer).

Cp° = A + B*t + C*t2 + D*t3 + E/t2
H° − H°298.15= A*t + B*t2/2 + C*t3/3 + D*t4/4 − E/t + F − H
S° = A*ln(t) + B*t + C*t2/2 + D*t3/3 − E/(2*t2) + G
Cp = heat capacity (J/mol*K)
H° = standard enthalpy (kJ/mol)
S° = standard entropy (J/mol*K)
t = temperature (K) / 1000.
