Enthalphy of reaction lab report

Authors Avatar by neilsanghrajka (student)

Aim:

 To determine quantitatively the enthalpy of reaction between copper(II) sulfate and zinc metal.

Qualitative Observations:

Red flakes were seen on the stirrer and the bottom of the copper calorimeter.

The solution turned colorless.

Heat energy was liberated

Data Collection

Volume of CuSO4 taken (V)  = 25cm3

Uncertainty in volume (∆V) = ± 1 cm3

Mass of  CuSO4 taken (M) = 25g

Join now!

Uncertainty in weighing scale (∆M)  =  ± 0.01 g

Mass of Zinc taken (m) = 2g

Uncertainty in mass of zinc (∆m) = ± 0.01 g

Specific Heat capacity of CuSO4 (c) = 4.184 J/g°C

Data Processing

Graph of temperature Vs time when zinc powder was added to Copper Sulfate

Intitial temperature (t1) = 27 °C

Final temperature (t2) = 65 °C

Change in temperature (∆T) = (65-27) °C  => 38°C

Uncertainty in change of temperature = 0.2 + 0.2 => ±0.4°C

Total Heat absorbed by CuSO4 (Q) = ...
