The Relationship between Heat and Amount of Reaction

1.0Aim:The aim of this experiment is to check up on the relationship betwixt the invoke and step of respondion of an experiment. 2.0Theory:When an acid response (i.e. HCl) is mixed with a resoluteness of a base (i.e. NaOH), hydrogen ions from the acid react with hydroxide ions from the base, thereby forming peeing. This chemical reception causes combust to be released, resulting in the temperature of the answer miscellanea wage hike:H+(aq) + OH-(aq) H2O(l)In this experiment, several reaction diversenesss will be made, severally containing various concentrations of acid and hydroxide closures. As the volumes of the reaction compartmentalizations are the same, the temperature changes are relative measures of the amount of heating system 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 severally of the acid theme and hydroxide solution (as per get in 4.1) was mensurable for reaction mixture 1. 2.The acid solution was pored into a test tube where its temperature was metric 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 essence on was metrical and recorded. 5.Steps 1-4 were repeat 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.
