Abstract
The purpose of this lab is to find out the molar enthalpy change of neutralization by mixture sodium hydroxide and hydrochloric acid. To get the result use some related materials and thermometer to measure the temperature of each solution. The formula to describe this mixture reaction is HCl + NaOH → NaCl + H2O (Sodium hydroxide combined with Hydrochloric acid)
Purpose
To determine the molar enthalpy change of neutralization, for the reaction of aqueous sodium hydroxide and aqueous hydrochloric acid.
Hypothesis
If Hess’ law is used to calculate the molar enthalpy of combined for HCl and NaOH using experimentally determined enthalpy values, then the final result will be more specific. This is because Hess’ law states that the sum of the enthalpy pages of the intermediate reactions, should equal the enthalpy change of the target reaction.
Materials
Coffee-cup calorimeter | Strning rod | Two 100 ml graduate cylinders | 1.0 mol/L Sodium hydroxide NaOH (aq) | thermometer | 1.0 mol/L Hydrochloric Acid HCl (aq) |

Procedure
Safety---before doing the lab, make sure already read the lab safety guidelines. (MSDS of sodium hydroxide and hydrochloric acid). All things that were unrelated and corrosive to the experiment should be clear off the benches. Goggles and glove should be kept on all the time.
To start this lab need assemble two coffee-cup calorimeter, each assemble coffee-cup have a nested polystyrene cups and upside down cup. for two assemble cup one using the graduated cylinder measure 50 ml of 1.0 mol/L Sodium hydroxide NaOH (aq) and another cup using the graduated cylinder measure 50 ml of 1.0 mol/L Hydrochloric Acid HCl (aq). Using the thermometer to measure and record the initial temperature of each
