The Relationship between Heat and Amount of Reaction

1.0Aim:The aim of this experiment is to canvas the relationship in the midst of the fire and nitty-gritty of respondion of an experiment. 2.0Theory:When an acid answer (i.e. HCl) is mixed with a resolvent of a base (i.e. NaOH), henry ions from the acid react with hydrated oxide ions from the base, thereby forming urine. This chemical reaction causes combust to be released, resulting in the temperature of the reaction miscellanea climb:H+(aq) + OH-(aq) H2O(l)In this experiment, several reaction mixs will be made, one after another containing various concentrations of acid and hydrated oxide effects. As the volumes of the reaction motleys are the same, the temperature changes are relative measures of the amount of erupt 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 resolving power and hydroxide solution (as per solve 4.1) was mensurable for reaction mixture 1. 2.The acid solution was pored into a test tube where its temperature was mensural 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 give way on was reason and recorded. 5.Steps 1-4 were restate once more(prenominal) 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.
