Mongana basics: part 16 – study of the quality and characteristics of oil
MENON, N. Ravi

This has been studied on samples of oil stored in sealed tubes. It is virtually impossible in that case to determine the value of the reaction constant k because a plot of logarithm of acidity against time leads to curves having their concavity towards the t axis. The apparent rate of the reaction decreases very quickly as the reaction proceeds. Furthermore, aberrant results are recorded frequently owing to the very small amounts of moisture to be determined
