Material Safety Data Sheet (MSDS) of Iodine solution
(not iodine)
(the solution used in starch experiments)
Step by step
Solved in 3 steps
- Water acts as a very effective solvent. True or falseTable of caffeine standards concentration Sample Conc, ppm Std1 16 Std2 32 Std3 48 Std4 64 Std5 80 If the volume used to make 100 mL of std 1 is 2 uL what is the concentration in M used to make a standard calibration curve? The standards are going to be used to build calibration curve to analyze caffeine in an energy drink. If 500 mL of the energy drink has target of 400 mg caffeine, how will you prepare the sample if you need 10 mL for the analysis ? . Caffeine MM=194.19 g/mol.900 mL saturated solution (potassium sulphate) was made at 30 degrees celsius. If the solution is heated to 50 degrees celsius, how much more potassium sulphate can dissolve now? Typed out would be preferred, or neat handwriting.
- “Atomic absorption spectroscopy (AAS) and UV-Vis spectroscopy is similar in principles”. Do you agree with this statement? Explain briefly.Recalling that a beaker of water is three dimensional what is the three dimensional shape of the micelleTRUE OR FALSE Palmitic oil is (soluble) to hot ethanol and chloroform. The lipid samples used in the experiment were (all complex lipids)
- Your supervisor asks to make 350 mL of a 0.75% (w/v) starch solution using a 5% (w/v) stock solution. You have calcuated how much stock solution you need. But, how much water (in mL) will you need to add to the stock to achieve the correct final concentration?A prescription asked for a 500 mL 12% dextrose solution. How would you prepare the prescription if the available dextrose solutions in the pharmacy are 10% and 20%?The labware we used in Quant Lab is divided into “qualitative” or “quantitative” analytical purpose. One of the important laboratory skills we learned is to know what specific apparatus is appropriate for the task at hand. For the following procedures, which SPECIFIC glassware, or balance ( CORRECT NAMES, be specific ) should be used? Mix K2Cr2O7 and KI solutions to be ready for titration. The mixture container is _______________ Measure the mV values of fluoride standard and sample solutions. Theoretically, the solution containers should be _______________________ Weigh 1 g solid KSCN that is poured into the thiosulfate – iodine titration. __________________
