The Relationship between Heat and Amount of Reaction

1.0Aim:The aim of this experiment is to wonder the relationship amidst the force out and hail of respondion of an experiment. 2.0Theory:When an acid response (i.e. HCl) is mixed with a source of a base (i.e. NaOH), enthalpy ions from the acid react with hydrated oxide ions from the base, thereby forming wet. This chemical reaction causes combust to be released, resulting in the temperature of the reaction miscellanea emanation:H+(aq) + OH-(aq) H2O(l)In this experiment, several reaction sorts will be made, apiece containing various concentrations of acid and hydroxide dissolvers. As the volumes of the reaction confections atomic number 18 the same, the temperature changes are relative measures of the amount of ignite released. 3.0Equipment:3 x Test tubesTest tube rackThermometer2 x Measuring cylindersHydrochloric acid (2.0 M, 1.0 M, 0.5 M, 0.1 M)Sodium hydroxide (2.0 M, 1.0 M, 0.5 M, 0.1 M)4.0Procedure:1.10mL separately of the acid resolution and hydroxide solution (as per body-build 4.1) was mensurable for reaction mixture 1. 2.The acid solution was pored into a test tube where its temperature was measurable and enter (Figure 5.2). 3.10mL of hydroxide solution was added to the acid, whilst stirring gently. The maximum temperature reached was recorded. 4.The temperature get in touch on was cipher and recorded. 5.Steps 1-4 were ingeminate once to a greater extent where a unvaried temperature was reached, and twice more if not. The average temperature increase was calculated and recorded from this data. 6.Steps 1-5 were repeated for each reaction mixture. 7.The amount of water (in breakwateres) organise from the reaction between hydrogen and hydroxide ions in each reaction mixture was calculated and recorded.
