When 25.0 ml of 0.500M

Question

HCI is added to 25.0ml of 0.500M KOH in a coffee cup calorimeter at 23.50C, the temperature rises to 30.17C. Calculate delta H of this reaction ( assume density of solution = 1g/ml)

Answer 1

NaOH + HCl ==> NaCl + H2O
q = mass H2O x specific heat H2O x (Tfinal-Tinitial)
mols H2O formed is M x L = 0.0125
dH = q/0.0125 J/mol
