2.95g of sodium bicarb how much water to add to make 1.0 M solution 4.25g of Sodium carbonate how much water to add to make 1.0 M solution. Please show all the work very clearly even little steps to help me understand. "You need to create a 1.0 M solution of sodium bicarbonate (NaHCO3 – baking soda). Your lab kit has a bag of sodium bicarbonate to use for this portion of the experiment. Write “sodium bicarbonate” on a sample...

1. What was the sodium sulfite used for the experiment below? 2. What material could still be in the ether layer of the experiment below? To a 3.0 mL conical vial containing a spin vane and equipped with an air condenser, add 20 uL of acetophenone and 700 uL of household bleach ( NaOCl, 5% available). Dispense both reagents in the hood! Stir the mixture at room temperature for thirty minutes. Add approximately 5.0 mg of sodium sulfite and stir...

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...

Grignard Reaction with a Ketone: Triphenylmethanol Introduction: The purpose of this lab is to prepare phenylmagnesium bromide, a Grignard reagent, and react it with benzophenone to give triphenylmethanol. Grignard reagents are very reactive and must be synthesized in an environment free of water or any other source of potential proton donor. Once made, the Grignard reagent will do a nucleophilic attack on the carbonyl carbon of the ketone, benzophenone. The result is an alkoxide that is then protonated to give...

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...
