t to determine the enthalpy of neutralization, you will construction a time verus temperature graph. why is this graph necessary?
Homework Answers
Time versus temperature graph is required to determine
equivalence point of titration .as acid is mixed with base heat is
evolved during process since neutralisation reaction is exothermic
in nature.On adding acid with base temperature increases till
equivalence point after completion of reaction temperature of
system start decreasing.through point of inflection of curve we can
determine equivalence point.
