In one of the General Chemistry experiments, you used a coffee-cup calorimeter to measure the heat of neutralization of selected acid-base reactions. The calorimeter consisted of two nested Styrofoam cups with a cardboard lid. A temperature probe was lowered in the solution through a hole in the lid. Is a coffee-cup calorimeter a constant-volume or a constant-pressure device? Is a coffee-cup calorimeter adiabatic? The coffee-cup calorimeter was calibrated by using the neutralization reaction between sodium hydroxide and hydrochloric acid. The...
Molar heat of Neutralization
A student collected the following data while demonstrating the molar heat of neutralization of a monoprotic acid, HA, with NaOH. Calculate the molar heat of neutralization of this acid with NaOH. Assume that the specific heats of the solutions are the same as watera) Temperature of HA and NaOH before mixing 23.7 degrees celciusb) Concentration of HA ...
