bitterness of phenylthiocarbamide‚ an organic compound used in genetics‚ and the ability and response of the tasting sodium benzoate paper‚ a food preservative. It is claimed that there is a direct relationship between the genes that control the tasting abilities of these two substances‚ primarily that if you had the ability to taste PTC‚ you would have a specific taste response for sodium benzoate‚ as well. After the experiment results were analyzed‚ it was determined that there is no direct correlation

was performed at Texas State University – San Marcos in the Chemistry lab. The concentrations used in the experiment were 0.5M of sodium hydroxide and 0.5M of sodium hypochlorite. The concentrations of the solutions found in the dumpster were calculated to be .806 M (both sodium hypochlorite and sodium thiosulfate as well). This was found by taking the 6.0% (by mass) sodium hypochlorite and multiplying it by 1 gram of solution‚ 1000 mL and 1 mol NaClO. This result was then divided by the result of 100g

The most commonly used thickeners for printing one cotton fabric is sodium alginate‚ but in view of its high price‚ partly substituting guar gum represents an acceptable alternative. Therefore‚ an attempt was made to print cotton fabric with sodium alginate and guar gum and compare its property and cost to the samples printed with sodium alginate. Methodology White cotton fabric having counts of 100 ends and 100 picks with the weight of 100 gm/m2

concentration between 0.05 mol dm-3 and 0.15 mol dm-3 and my aim is to find out exactly what its concentration is. To do this I have been given solid anhydrous sodium carbonate and a range of pH indicators. With this solid anhydrous sodium carbonate I can make a solution of known concentration by mixing it with distilled water to make sodium carbonate solution (which is an alkali solution). Once I have mixed this solution I can use it to perform a series of titrations to find out accurately what the
