PAPER CROMATOGRAPHY • Define chromatography • Demonstrate an understanding of the process of chromatography • Describe the steps involved in a chromatography investigation Explanation Coloured inks are often made up of several different inks. Each colour of ink will get carried a different distance by the water, allowing you to see all of the different inks. Try this with different colours to see what actually goes into a colour. This technique is called chromatography and can be used in chemistry to find out what is in an unknown mixture. II. Materials .Felt tip pens (non-washable) . Kitchen roll .A bowl or cup . Water • Scissors III. Health and safety • Make sure that you thoroughly clean any equipment after the experiment before using for food IV. Procedure Method 1 1. Take a sheet of kitchen roll and draw a simple picture with a non-washable felt tip pen. 2. Place the sheet over an empty bowl. This is to keep the paper from getting too wet. 3. Carefully add a few drops of water…

1. A 25-mL specific gravity bottle was found to weigh 46.05 g when filled with water, and 52.93 g when filled with the ophthalmic solution. If the empty specific gravity bottle weighs 21.04 g, what is the specific gravity of the ophthalmic solution? a 0.784 b 0.870 c 1.149 d 1.275
2. The goal behind suction filtration is to remove soluble impurities that are on the surface of the crystals. Therefore, why can't you simply use suction filtration instead of recrystallization to purify an impure solid?
Why is fractional distillation more efficient than simple distillation when purifying liquid mixtures?
What are the types of gravimetric methods? Give an examples where each method is used in an analysis. What is particulate gravimetry? When do we use this technique?
You were tasked to separate the components of a mixture containing silica, sodium chloride and charcoal. TNāCI dissolves in water while silica and charcoal are not water-soluble. Only charcoal dissolves in carbon disulfide. a. Write a short experimental procedure to carry out the separation of the mixture. b. Given the following data, determine the percentage of charcoal, sodium chloride and silica. Mass (g) Mass of beaker 100.000 Mass of beaker + mixture 110.000 mass of evaporating dish 62.000 mass of evaporating dish + solid after evaporation of water 65.000 Mass of beaker + charcoal + silica after evaporation of excess water 117.000 mass of beaker + silica after decanting dissolved charcoal and drying 113.545

During a routine check of the fluoride content of Gotham City's water supply, the given results were obtained from replicate analyses of a single sample: 0.815 mg/L, 0.789 mg/L, 0.811 mg/L, 0.789 mg/L, and 0.815 mg/L. Determine the mean and 90% confidence interval for the average fluoride concentration in this sample. Report the mean and the confidence interval using the "real rules" for significant figures. mean: 0.804 90% confidence interval: 2.32 x10-4 Incorrect mg/L mg/L

A group of students performed a melting point experiment to study the physical properties of ionic and covalent solids. The data collected are shown in the table. Solid Sample Melting Point (oC) Time Elapsed (min) Table Sugar (sucrose) 186 18 Table Salt (sodium chloride) 500 (not observed) 30 Paraffin Wax 37 4 Vegetable Lard 50 >5 Using the information contained in the table, what is the BEST explanation for the results?A The melting point of sodium chloride was not observed because ionic solids do not melt, whereas sugar, wax, and lard melted because they are softer than salt.B The melting points of covalently bonded solids tend to be lower than ionic solids. The melting point of sucrose was greater than the wax or the lard because sucrose has stronger bonds than wax or lard.C The melting point of sodium chloride was not observed because ionic solids are composed of positive and negative ions that do not melt; whereas, the…
