Molar Enthalpy of Neutralization In this experiment, you will measure the temperature change that occurs during the neutralization of a strong acid, hydrochloric acid by a strong base, sodium hydroxide. The acid and base are each dissolved in water 1.00 M solutions. You will initiate the reaction by mixing equal volumes of the acid and the base solutions. The following equation describes the neutralization reaction: HCl(aq) + NaOH(aq) ⟶ NaCl(aq) + H2O(l) The neutralization reaction is exothermic, and the energy released as heat by the neutralization is absorbed by the surrounding solution, increasing the temperature of the reaction solution. The heat of the system, qrxn, can be determined from the heat of the surroundings with the equation −qrxn = qsurr = msolutions ⋅ c ⋅ ΔTsolutions. Assume that the acid solution, base solution, and mixture have the same density as the density of pure water, 1.00 g/mL, and they provide msolutions, the mass of the reaction solution. Also assume that the specific heat capacity of the reaction solution is the same as that for pure water, 4.184 J⋅g−1⋅deg−1. Ti is the initial temperature of the acid and base solutions, and Tf is the highest temperature attained by the reaction solution after they are mixed. From the calculated value of qsurr and the number of moles of acid or base consumed in the reaction, you can calculate the enthalpy of reaction, ΔrH∘. Here we introduce a preferred notation, using the term ΔrH∘ in place of ΔH. The subscript "r" is for “reaction”, and the degree symbol (∘) indicates a reaction that is occurring at standard pressure and concentration. For common types of reactions, the subscript will be one or more letters, e.g. “vap” for “vaporization”. The instructor and LA will demonstrate a neutralization reaction. You need to record the measurements and determine an experimental value for the molar enthalpy of neutralization. Concentration of the acid solution: 1.0 M Concentration of the base solution: 1.0 M Volume of acid solution used: 30 mL Volume of the base solution used: 30 mL Initial temperature of the acid solution: 22.1°C Initial temperature of the base solution: 22.1°C Final Temperature of Reaction Solution: 28.7°C qrxn: J ΔneutralH∘: kJ/mol I need help finding the qrxn and ΔneutralH∘ with the info given.
