The Relationship between Heat and Amount of Reaction

1.0Aim:The aim of this experiment is to investigate the relationship between the force out and total of respondion of an experiment. 2.0Theory:When an acid response (i.e. HCl) is mixed with a radical of a base (i.e. NaOH), hydrogen ions from the acid react with hydrated oxide ions from the base, thereby forming weewee. This chemical response causes combust to be released, resulting in the temperature of the reaction miscellanea rising:H+(aq) + OH-(aq) H2O(l)In this experiment, several reaction potpourris will be made, separately containing various concentrations of acid and hydrated oxide stems. As the volumes of the reaction mixtures are the same, the temperature changes are relative measures of the amount of heat 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 each of the acid solution and hydroxide solution (as per Figure 4.1) was mensurable for reaction mixture 1. 2.The acid solution was pored into a test tube where its temperature was metrical 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 cooperate on was calculate and recorded. 5.Steps 1-4 were repeated once more 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.
