Considerable heat is evolved when concentrated HCl is added to water. true or false
Considerable heat is evolved when concentrated HCl is added to water. true or false
Homework Answers
Answer: True
HCl first dissociates into ions (enthalpy of dissociation) - endothermic
next these ions are hydrated (solvolysis or solvation or enthalpy of hydration) -exothermic
Overall it is exothermic, so heat is released.
Hope this helped you!
