PART B. HEAT OF SOLUTION REACTION Obtain a sample bottle with an unknown ionic salt. Record its identification letter. Gently dry the inside of the calorimeter and weigh it. If the calorimeter is not dry, you will not be able to accurately find the mass of water in your calorimeter. Add about 50 mL of distilled water and weigh again. Measure the water's initial temperature. Use a plastic weighing "boat" set to zero on the balance and use it to...

Lab 14 Heat of Reaction Objective: To experimentally determine the heat of reaction for two exothermic reactions. Consider the following equations. (1) Mg(s) + 2HCI → MgCl2(aq) + H2(g) Hz(8) AH = ? (2) MgO(s) + 2HCl(aq) → MgCl(aq) + HOH (1) AH2 = ? The reactions represented by equations (1) and (2) will be our experimental work for today. Background: The heat given off or gained in a reaction is commonly called the heat of reaction. A reaction that...

7-3: Analysis of a Ferrous Chloride Sample Titrations provide a method of quantitatively measuring the concentration of an unknown solution. This is done by delivering a titrant of known concentration into an analyte of known volume. (The concentration of an unknown titrant can also be determined by titration with an analyte of known concentration and volume.) In oxidation-reduction (redox) titrations, the voltage resulting from the mixture of an oxidant and reductant can be measured as the titration proceeds....
