Enthalpy of Neutralization of Strong Base and Acid

Authors Avatar by aadharshd (student)

Experiment 1: Enthalpy of Neutralization of Strong Acid with Strong Base

Strong Base: Sodium Hydroxide (NaOH)

Strong Acid: Hydrochloric Acid (HCl)

Reaction: HCl (aq) + NaOH (aq) --> NaCl (aq) + H2O (l)

Uncertainty in Stopwatch = ± 0.05s

Least count of Thermometer = 1oC

Uncertainty in Thermometer = 0.5oC

Volume of Acid Taken = 5 ml

Volume of Base Taken = 5 ml

Least count in Measuring cylinder = 1ml

Uncertainty in measuring cylinder = ± 0.5ml

Molarity of Acid = 1M

Molarity of Base = 1M

To find enthalpy we can use this equation:

Where E = Energy transfer between system and surroundings
            m = Mass of Substance
            c = Specific Heat capacity of substance
            ∆T = Change in Temperature
