Examples of effect: Flammable; liquids form compounds with the air which can become explosive; produce flammable gases with water or can self-combust. Safety: Keep away from open flames and sources of heat; close containers tightly; store in a fire-safe manner.
Examples of effect: Damage metals and burn body tissues; may cause serious eye damage. Safety: Avoid contact; wear safety spectacles and gloves. In the event of contact with eyes and skin, rinse with water.
H226-H314 Flammable liquid and vapour, causes severe skin burns and eye damage.
P210 P280 P301+P330+P331 P303+P361+P353 P305+P351+P338 P310 Keep away from heat, hot surfaces, sparks, open flames and other ignition sources. No smoking, wear protective gloves/protective clothing/eye protection/face protection, IF SWALLOWED: rinse mouth. Do NOT induce vomiting, IF ON SKIN (or hair): Take off immediately all contaminated clothing. Rinse skin with water [or shower], IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present, and easy to do. Continue rinsing, immediately call a POISON CENTER/doctor.

Description

Iodine Value Determination

The iodine value is a measure of the unsaturated fatty acids in glycerides. The more olefinic double bonds there are in the fat, the higher the iodine value.

Peroxide Value Determination

The peroxide value of a substance denotes how much peroxide it contains. In a mixture of glacial acetic acid and chloroform, the peroxide oxidises the iodide into elementary iodine. The resulting quantity of iodine is then back-titrated using a thiosulphate solution (where a starch solution is used as the indicator). The blank solution tested in parallel is used to calculate the results.

Barfoed’s test:

Barfoed’s test is used to distinguish monosaccharides from disaccharides, oligosaccharides and polysaccharides. Barfoed’s reagent is added to the sugar solution, which is then heated for a few minutes in a water bath. Monosaccharides turn a reddish colour, while disaccharides only react after they have been boiled for a longer period.
