Questiоn 11 When аqueоus sоlutions of potаssium hydroxide аnd nitric acid are mixed together, an exothermic reaction occurs. The diagram shows the apparatus used in an experiment to measure the temperature increase. This is the student's method. use the larger measuring cylinder to add 25 cm3 of aqueous potassium hydroxide to the polystyrene cup. record the steady temperature. use the smaller measuring cylinder to add 5 cm3 of dilute nitric acid to the cup, stir the mixture with the thermometer. record the highest temperature of the mixture. continue adding further 5 cm3 portions of dilute nitric acid to the cup, stirring and recording the temperature, until a total volume of 35 cm3 has been added. a The diagram shows the thermometer readings at the start and at the end of one experiment. (2) Complete the table to show: the thermometer reading at the start of the experiment the temperature rise in the experiment. Only fill in the two missing values in the table. Thermometer reading at end in oC 26.8 Thermometer reading at start in oC Thermometer rise in oC b Another student uses the same method, adding the dilute nitric acid from a burette. The table shows his results. This is the student's graph. The point where the lines cross represents complete neutralisation. bi Identify the maximum temperature reached during the experiment. (Read from the graph accurately) (1) bii Identify the volume of dilute nitric acid that exactly neutralises the 25 cm3 of aqueous potassium hydroxide. (Read from the graph accurately) (1) c Another student records these results (4) Volume of aqueous potassium hydroxide 20.0cm3 Starting temperature of potassium hydroxide 18.5oC Maximum temperature of mixture 30.0oC Volume of dilute nitric acid 20.0cm3 Calculate the heat energy (q) released in this experiment. c = 4.2 J/g / °C mass of 1 cm3 of mixture = 1 g q = mc
