Question

Electrolytes, Concentration and Dilution of Solutions n this part of the experiment, you will make a dilution of a stock solution of known concentration and calculate the concentration of the dilute solution. DILUTION OF A STOCK SOLUTION PART C: Measurements and Observations Procedure Check out a 100-mL volumetric flask from your instructor. Fill test tube about 2/3 concentration of the active ingredient from its label including units. Record 1. orlt O " concentration of active ingredient. full of "Magic 2. per tooml salutien Elixir" solution. Record the given observations of solution appearance: your observations of the solution. Use your 10 mL graduated cylinder to 3. measure 7 mL of the elixir solution from your test tube (leave the remaining solution in your test tube for volume of "Magic Elixir transferred-IS m color comparison). Read and record the volume to ± 0.05 mL. Pour this solution into the 100-mL volumetric flask. Add deionized water to the flask slowly with swirling until the liquid level nears the neck of the flask. Continue to add water with your squirt bottle and/or a medicine dropper until the bottom of the meniscus is exactly at the calibration marking in the neck of the flask. Stopper the flask, and while holding the stopper, carefully invert to mix the contents thoroughly Pour out about 3 mL of the diluted solution into a clean, dry test tube. 4. observations of the diluted solution compared to stock solution: Compare the colors of the stock and diluted solutions in your two test tubes. utian has a 5. All solutions can be poured down the Cleah Colou lwith Stone drain. Electrolytes, Concentration and Dilution of Solutions C8. Wh at volume of your diluted solution would be needed to obtain 0.050 grams of Vitamite? C9. If the recommended dosage of Vitamite is 0.50 mg Vitamite per kg of body weight, how many mL of the diluted elixir solution should be given to a 100.-lb person?
