Question
plot a temperature(y-axis)t time (x-axis) graph for mixing the acid and base with a line of mixing for each determination on excel. Then determine the following for each determination
molarity of base (M)
molarity of acid
volume of acid (mL)
volume of base
T initial of acid
T initial of base
T final of mixture
temperature change
heat absorbed by the reaction mixture (J)
heat absorbed by calorimeter, thermometer, and stirrer (J)
total heat absorbed (J)
number of moles and acid used
molar enthalpy of neutralization kJ per mole of acid
mean molar enthalpy of neutralization, kJ mole of acid
Explanation / Answer
Plot of temperature vs time for 1st determination:
Initial temperature of base can be obtained from equation for Series 2: first equation on top.
Ti (base): Put x = 0 and y = 20.94
Ans: 20.94°C
Ti (acid): Series 3; 2nd equation; put x = 0 and y = 20.62
Ans: 20.62°C
Tf: Obtain this from Series 4; put x = 0 and y = 34.879
Ans: 34.879°C
To calculate all the other results, I need the data, namely, weights of acid and base used, the volumes of acid and base used. Kindly update the complete experiment.
