Acids and Bases

Heat of Neutralization: HCl(aq) + NaOH(aq)

Heat of Neutralization: The initial temperature of 50.0 mL of 3.0 M HCl and a 3.0 M NaOH are measured using a digital thermometer probe. The HCl and NaOH react a calorimeter. The final temperature of the resultant solution is measured. The heat exchanged between the chemcial reaction and the solution is calculated. The change in enthalpy of the reaction, ∆H, the heat of neutralization is determined.

Limiting Reactant: Reaction of Mg with HCl

Limiting Reactant: Reaction of Mg with HCl The amount of hydrogen gas produced by the reaction of three different quantities of Mg in the same numbere of moles of HCl is observed. Students are provided with the moles of magnesium and moles of hydrochloric acid and are asked to predict the relative amount of hydrogen gas produced in each reaction. Students determine the limiting reagent in each flask.
