    Chemistry: Change in Temperature in the Production of Silver Chloride

    This content was COPIED from BrainMass.com - View the original, and get the already-completed solution here!

    When solutions containing silver ions and chloride ions are mixed, silver chloride precipitates:

    Ag+(aq) + Cl-(aq) ?AgCl(s) deltaH = -65.5 kJ

    Calculate deltaH for the production of 0.200 mol of AgCl by this reaction. Calculate deltaH for the production of 2.50 g of AgCl. Calculate deltaH when 1.500 mmol of AgCl dissolves in water. Please provide detailed explanation.

    Calculate deltaH for the production of 0.200 mol of AgCl by this reaction. Given the equation,

    Ag+(aq) + Cl-(aq) --> AgCl(s) deltaH = -65.5 kJ

    It tells that formation of 1 mole of AgCl liberates 65.5 kJ of heat. Hence, the heat liberated for the production of 0.200 mole AgCl can be computed using ratio and proportion:

    -65.5 kJ / 1 mol AgCl = x / 0.200 mol AgCl
    x = -13.1 ...

    Solution Summary

    This solution answers various chemistry problems involving solutions containing silver ions and chloride ions. The calculations done include: finding the heat from a reaction producing AgCl and the reaction of AgCl dissolving in water. Step by step calculations are provided.
