The Relationship between Heat and Amount of Reaction

1.0Aim:The aim of this experiment is to analyse the relationship in the midst of the passion and pith of respondion of an experiment. 2.0Theory:When an acid reply (i.e. HCl) is mixed with a effect of a base (i.e. NaOH), henry ions from the acid react with hydrated oxide ions from the base, thereby forming wet. This chemical reply causes combust to be released, resulting in the temperature of the reception miscellanea emerging:H+(aq) + OH-(aq) H2O(l)In this experiment, several reaction confections will be made, severally containing various concentrations of acid and hydrated oxide resolves. As the volumes of the reaction medleys atomic number 18 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 hydrated oxide (2.0 M, 1.0 M, 0.5 M, 0.1 M)4.0Procedure:1.10mL individually of the acid resolve and hydroxide solution (as per betoken 4.1) was mensurable for reaction mixture 1. 2.The acid solution was pored into a test tube where its temperature was heedful 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 tie in on was calculated and recorded. 5.Steps 1-4 were ingeminate once more than 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.
