Question

If 25.0 mL of a 0.100 M aqueous sodium hydroxide is mixed with 25.0 mL of a 0.100 M aqueous hydrochloric acid in a calorimeter at an initial temperature of 23.0 degrees Celsius, what is the enthalpy change of this reaction if the final temperature reached in the calorimeter is 25.5 degrees Celsius?

NaOH + HCl yields NaCl + H2O

Answer 5

50ml total solution
50g x 4.18 x ( 25.5-23.0)= 522.5 J
-335 J x 1kj/1000 J= -0.335 kj
