Determine the standard enthalpy change of the reaction between 50.0 mL of 0.200 M hydrochloric acid (HCl) and 50.0 mL of 0.100 M sodium hydroxide (NaOH) at 25°C. The reaction is a neutralization reaction between HCl and NaOH, and the products are water and sodium chloride (NaCl). The molar enthalpy of formation of NaCl is -411.2 kJ/mol, and the specific heat capacity of the aqueous solution is 4.18 J/g°C.
