This is the student's method. pour 20 cm3 of sodium hydroxide solution into a polystyrene cup record the temperature of the sodium hydroxide solution add 20 cm3 of dilute hydrochloric acid and stir the mixture record the highest temperature of the mixture a(i) Give the formula of the ion that causes sodium hydroxide solution to be alkaline. (1) a(ii) Suggest a pH value for the dilute hydrochloric acid. (1) b Explain why a polystyrene cup is used in this experiment. (2) c See diagram 4c in the diagram pdf. The diagram shows the thermometer readings at the start and at the end of the experiment. Use the readings to complete the table, giving all values to the nearest 0.1 °C. Temperature in °C at end Temperature in °C at start Temperature change in °C (3) d Another student does the experiment, but uses 25 cm3 of sodium hydroxide solution and 25 cm3 of dilute hydrochloric acid. She records a temperature change of 5.2 °C. Calculate the heat energy (Q) in kilojoules (kJ) released in this reaction. [mass of 1.0 cm3 of solution = 1.0 g] [for the solution, c = 4.2 J / g / °C] Q = ........................................................... kJ (4) [11] Do not upload here - use the upload quiz
