Abstract

The study investigated Allium sativum L bulbs extracts as olfactory indicator for visually impaired Chemistry students as an alternative to Methyl orange and Phenolphthalein. In this study, concentrations of 0.1M, 0.5M, 1M and 2M HCl and NaOH were used for the Olfactory Titration using Allium sativum L olfactory indicator extracts, Methyl orange and Phenolphthalein. The results of the study revealed that the mean titre values for olfactory titration of 0.1M HCl and 0.1M NaOH using Allium sativum L olfactory indicator and Methyl orange were 13.000 and 0.000 with S. D Error of 0.000, signifying that Allium sativum L olfactory indicator, for this study cannot conveniently replace Methyl orange in 0.1M HCl: 0.1 M NaOH olfactory titration. The mean titre values for the Allium sativum L indicator used for olfactory titration of 0.5M HCl: 0.5M NaOH showed a great significant difference. For the olfactory titration of 1M HCl: 1M NaOH, the mean titre values of 3.0667 for Allium sativum L olfactory indicator; 3.2000 for Phenolphthalein and 3.1333 for Methyl orange indicators were recorded. The results revealed an almost total agreement, signifying that at a molar concentration of 1, Allium sativum L olfactory indicators can equivocally replace Phenolphthalein and Methyl orange indicators. Interestingly, the mean titre values for olfactory titration of 2M HCl: 2M NaOH using olfactory indicators and Phenolphthalein were, Allium sativum L = 5.000 and Phenolphthalein = 5:000, showing that Allium sativum L can be used as an alternative to Phenolphthalein indicator for concentrations of 2M. For the same 2M, the mean titre value for using Methyl orange was 24:000, almost 5x>the two indicators. Thus there is a very significant difference in the mean titre values of Allium sativum L olfactory indicators and that of Methyl orange. It is also concluded that the use of Allium sativum L bulbs extracts as olfactory indicators is of great economic benefits as it is affordable, bioavailable, bioactive, ecofriendly, ease of preparation, non-carcinogenic and gives accuracy and very near or same precision with visual indicators.. The Allium sativum L indicators gives a strong and more stringent steady ordour at completion of the reaction.
