# 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.

#### Solution Preview

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.
