In this experiment, the student measured the change in temperature not for the system itself but for the surroundings (aqueous solution). The solution is very diluted and we can safely consider its specific heat and its density to be the same as for pure water: c=4.18 J/g-ºC and d=1.00 g/cm
In the SECOND experiment, the student mixed in a coffee cup calorimeter 58.0 mL of 0.25M H2SO4 solution and 42.0 mL of 0.60M NaOH solution.
Do you think that the change in temperature in the SECOND experiment was similar to the one recorded?
a. T2 b. T2 =T1: in the second experiment, the same amount of water was formed because hydroxide ion was a limiting reagent
c. T2=T1: in the second experiment, the same amount of water was formed because sulfuric acid was a limiting reagent
d. T2>T1: in the second experiment, more amount of water was formed because hydrochloric acid was the limiting reagent
