Analytical Calculations:

By knowing the concentration of either the titrant or the sample, concentration of unknown may be calculated from the volume added to reach the end point. Heat of reaction is, in general, obtained from the Eq. 11.17 - 11.19. However, in practice a graphical method is followed. Heat capacity at the mid point of the curve is obtained by extrapolating the part of the curve in Region III back to region II and thus measuring Q from the baseline to the extrapolated line at the mid point of titration
