Textbook Question
Chapter 8, Problem 90QAP
Consider a metal ion A2+ and its nitrate salt, In an experiment, 35.00 mL of a 0.217 M solution of A(NO3)2 is made to react with 25.00 mL of 0.195 M NaOH. A precipitate, A(OH)2, forms. Along with the precipitation, the temperature increases from 24.8°C to 28.2°C. What is ΔH for the precipitation of A(OH)2? The following assumptions can be made.
• The density of the solution is 1.00 g/mL.
• Volumes are additive.
• The specific heat of the solution is 4.18 J/g
°C.
