Reaction between Iron(III) Nitrate and Sodium Hydroxide. 2. Take two cylinders and fill one (full) with sodium hydroxide solution and other with Iron(III) nitrate solution. 3. Pour suitable amount (around 50 ml) of sodium hydroxide from the cylinder using a funnel into a Erlenmeyer flask. 4. Take a test tube and fill it half with the iron(III) nitrate solution from the cylinder with the use of a funnel. 5. Place the test tube containing iron(III) nitrate solution into the Erlenmeyer flask containing

Alka-Seltzer Rocket Formal Lab Report Abstract In the Alka-Seltzer Rocket lab one was to experimentally determine how much (grams) Alka-Seltzer and water in mL‚ is needed to launch the rocket the highest/longest distance in cm. Also to experimentally determine the % NaHCO3 in the tablet using the information from the highest/longest distance. Calculate the error and % error of NaHCO3 in an Alka-Seltzer tablet and to determine the limiting reagent for the highest/longest distance traveled. Alka-Seltzer

Introduction! ! The Michelson Interferometer is commonly used to determine the wavelength of light or measure very small distances. It was invented by Albert Abraham Michelson and is commonly used in optical interferometry‚ a branch of physics involving a family of techniques one could use to extract information about waves by superimposing them. ! ! The original application of the Michelson Interferometer was to the famous Michelson-Morley experiment in 1887. Prior to Einstein’s

Determination of Vitamin C by an Iodometric Titration Purpose: The goal of this lab is to determine the concentration of vitamin C in juices and Real Lemon. A redox titration‚ involving an iodometric method‚ will be used to do the analysis. The samples will be classified by their Vitamin C content. Introduction: Although most mammals can synthesize vitamin C‚ or ascorbic acid (C6H8O6)‚ from sugars‚ man must ingest considerable quantities of this substance. The National Academy of Sciences recommends
