Acids and Bases

Using pH paper to measure the pH of solutions Computer Simulation

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.

Citric acid vs. Hydrochloric acid Concentration and Conductivity

pH measurement of acid, base and ionic salt solutions Computer Simulation Measure the pH of various solutions.

Acid-Base Titration Computer Simulation A visual approach to learning how to perform acid-base titration procedures, techniques anda the application of sstoichiometry to acid-base titration calculations

Compares conductivity of strong and weak acids and bases.

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.

Copper chloride solution forms a pale blue precipitate then a deep blue solution as ammonia is added.

Dry ice changes the colors of a universal indicator solution.
