We did a lab with a Styrofoam cup calorimeter, and we ended up having a molar enthalpy of -58 KJ/mol. The theoretical value is -56, which means we gained heat in the system...
our equation is: NaOH + 1/2 H2SO4 --> H20 +1/2 Na2 SO4 + 56 KJ
what do you think are some experimental errors that could have made us GAIN heat, when we were expecting to loose heat if anything... also our experimental error was 3.6 %
thank you any ideas are appreciated
