uncertain as to why someone did what they did. In a study by Gifford Weary and John A. Edwards (1994)‚ they define this uncertainty about one’s inability to comprehend or identify causal relationships or causal conditions in society as causal uncertainty (CU). Whether you are trying to make sense of why your best friend does not want to go out to the movies or why a stranger started talking to you in an elevator‚ people have this overwhelming urge to understand or reason the cause of another person’s behavior

EXPERIMENT 8 QUANTITATIVE DETERMINATION IODOMETRIC TITRATION OF COPPER CONCENTRATION IN AQUEOUS SOLUTION B Y RESULTS AND DISCUSSION Considered as moderately weak oxidizing agent‚ Iodine was used for the determination of strong reductants. Standard iodine solutions were found to have smaller electrode potentials as compared with the other oxidants‚ gaining them the advantage of imparting a degree of selectivity essential in the determination of strong reducing agents amid the presence

Benedict ’s solution contains Cu+2 ions that are blue in colour. This means that when Benedict ’s solution is added to clear transparent or translucent solutions‚ the solutions turn light blue due to the presence of the Cu+2 ions. Out of the 12 solutions‚ solution 10 (beer) was a light brown-yellow colour‚ while the remaining 11 were either transparent or translucent. Thus‚
