    By simply comparing the reactions that occurred when each metal was added to HCl‚ we are able to rank the reactions. Metals that reacted with HCl to produce hydrogen gas would be considered more active that those that exhibited no reaction. Therefore‚ the metal that reacted the most vigorously in acid would be the most reactive metal. In addition‚ the metal that

    solution of EDTA by titration against a standard solution made from calcium carbonate‚ CaCO3. Procedure: A 50-mL buret‚ a 250-mL volumetric flask‚ and 25- and 50-mL pipets were obtained from stockroom. The 0.5 g of calcium carbonate was weighted in a small 50-mL beaker. Approximately 0.4 g of the carbonate was transferred to a 250-mL beaker. 25 mL of distilled water was poured to the large beaker and 40 drops of 6 M HCl were added. Then‚ solution was heated until it just begins to boil. After boiling

    Patrica E. Sauza‚ Jelica D. Estacio Institute of Chemistry‚ University of the Philippines‚ Diliman‚ Quezon City 1101 Philippines Results and Discussion Eight Styrofoam ball calorimeters were calibrated. Five milliliters of 1M hydrochloric acid (HCl) was reacted with 10 ml of 1M sodium hydroxide (NaOH) in each calorimeter. The temperature before and after the reaction were recorded; the change in temperature (∆T) was calculated by subtracting the initial temperature from the final temperature.

    UNITS OF CONCENTRATION There are a number of different ways of expressing solute concentration that are commonly used. Some of these are listed below. Molarity‚ M = moles solute/liter of solution Normality‚ N = equivalents of solute/liter of solution Weight %‚ Wt % = (mass of solute/mass of solution) x 100% Parts per million‚ ppm = (mass of solute/mass of solution) x 106 Mass per volume‚ mg/L = mass of solute/liter of solution molality‚ m = moles of solute/mass of solvent mole fraction‚ χ = moles
