In a neutralization reaction involving 25.0cm3 of 1M sodium hydroxide and
25.0 cm3 of 1M ethanoic acid the following results were obtained. Assume that the density of solution is 1g/cm.
Temperature of Sodium hydroxide solution T1= 24.2 oC
Temperature of Ethanoic acid solution T2= 24.0 oC
Temperature of resulting solution after neutralization T4= 28.6 oC
Calculate the average temperature of acid and base T3
T3 = T1 + T2 = +=oC
