per year. Thiourea Dioxide (TDO or TUD) is also named as Formamidine Sulfinic Acid. Its appearance is white crystal powder. Thiourea Dioxide is a stable compound with no strong reducing and oxidizing ability‚ and its dissolvability is 26.7g/l (20 oC)‚while its PH is 5.0 in saturated solution. Thiourea Dioxide (TDO) appears terrific stable even in 20oC -30oC solution‚ but when it is under heat or catalysesing by alkali‚ it decomposes gradually to produce sulfoxylic acid through formamidine sulfinic

Preparation of Materials It is best to use limp green lettuce which has been left in an incubator at about 35 oC for an hour. This causes the cells to plasmolyse slightly. Viscozyme‚ pectinase and cellulase enzymes can be bought from NCBE. Do not dilute the enzymes. The enzyme solution

The problem is believed to have been first introduced by Greek astronomer Ptolemy back in 150 AD1 and then eventually noticed by 17th century Arabic mathematician Abu Ali al Hassan ibn Alhaitham (whose name was later Latinized into Alhazen)2 .

PRODUCTION OF CITRIC ACID Introduction: Citric acid is a White solid‚C3H4OH(COOH)3‚soluble in water and slightly soluble in organic solvents‚ which melts at 153 oC. Aqueous solutions of citric acid are slightly more acidic than solutions of acetic acid. Traces of citric acid are found in numerous plants and animals‚ because it is a nearly universal intermediate product of metabolism. Large amount of the acid are found in the juice of citrus fruits‚ from which it is precipitated by the

Fluid Mechanics CHE2161/MEC2404 Frictional Flow in Pipes Experiment : Friday 8.30-11.30am Conducted In : Fluid Mechanics Lab Abstract The main aim of this experiment was to show how the friction factor varies with Reynolds number by manipulating the flow rate of the fluid in a pipe. The main principle used in the experiment was the Bernoulli’s equation‚ taking major head losses into account. These major head losses were normally due to wall friction in the pipe and viscous
