[(+)-Co(en)3]I3•H2O Preparation Could you help me understand why this reaction happens for this procedure: dissolve [(+)-Co(en)3][(+)-tart]Cl•5H2O in 15 mL of warm water and add 0.25 mL of concentrated ammonia (15 M) solution. With stirring, add a solution of 17.0 g of NaI in 7 mL hot water. After cooling in an ice-water bath, filter the product using vacuum filtration and wash the crystals with an ice cold solution of 3.00 g of NaI in 10 mL of water. Wash the...

In the hood, place 100 mu L of aniline in a tared 10 times 75 mm (small) test tube. Place the test cube in a small beaker or Erlenmeyer flask to avoid spillage. Stopper the cube with a cork. Now, using a Pasteur pipet, add (with swirling) 0.5 mL of water, followed by three drops of concentrated HCI. Add 10 mg of decolorizing charcoal (we use the pelletized form, called Nonrit^TM) to...

Determine the theoretical yield and limiting reagent
Running the Reaction Add 0.100 g benzil and 0.30 mL 95% ethanol to a 3-mL conical vial. Place a spin vane in the vial and attach an air condenser. Heat the mixture with an aluminum block (90-100°C) while stirring until the benzil has dissolved (see inset in Tech- nique 6, Figure 6.1A). Using a 9-inch Pasteur pipette, add dropwise 0.25 mL of an aqueous potassium hydroxide solution' downward through the condenser into the...

1. In a small beaker mix together 5.0 mL of 0.10 M Co(NO3)2 . 6H2O with 5.0 mL of concentrated HCl. Be sure to mix thoroughly with your glass stirring rod. This is your equilibrium mixture. 2. Place 1.0 mL of your equilibrium mixture in a small test tube add 1.0 mL of concentrated HCl. Observe any color changes and state in which direction (if any) the equilibrium shifted. Place a new 1.0 mL sample of your equilibrium mixture in...

Acid/Base Extraction Liquid-liquid extraction is a technique that can be used to physically separate two substancesthat have varying solubility properties. Typically an aqueous solution can be extracted with anorganic solvent to isolate a compound or vice-versa. The specialized piece of glassware that isemployed for these types of separations is called a separatory funnel.In this experiment a mixture of benzoic acid and naphthalene will be purified using liquid-liquidextraction, more specifically an acid-base extraction. Since both compounds are soluble inethyl acetate (an...
