ecwer temperature P5-% In order to study the photochemical decay of aqueous bromine in bright sun- light, a small quantity of liquid bromine was dissolved in water contained in a glass battery jar and placed in direct sunlight. The following data were obtained at 25°C: Time (min) 10 20 30 40 50 60 ppm Br2 2.45 1.74 1.23 0.88 0.62 0.44 (a) Determine whether the reaction rate is zero, first, or second order in bro- mine, and calculate the reaction...

Experiment . the reduction of bencil (March 2020) Your name Sodium borohydride is a convert recent for the reduction of dehydes and ketones to 1" and 2 alcohols, respectively. The mechanism of the reaction - (below) is straightforward and is driven by boron's affinity for oxygen. In addition, given borohydride's remarkably low reactivity with OH groups under neutral and especially basic conditions, this reaction can be done in alcohol solvents. This means that (unlike LAH or Grignard reactions) no separate...

Process A. Preparation of 4-t-butylcyclohexene Assembling the equipment Fill the almost complete sand bath, place it on the base of the shelf, fix the thermometer with a clip and start heating until the temperature of the sand is - 110C. B. Mixing the reagents Using the plastic funnel, introduce 0.60-0.70 g of 4-t-butylcyclohexanol into a large, clean, dry test tube. Then add 10 drops of concentrated phosphoric acid, 3 drops of concentrated sulfuric acid and a pebble to moderate boiling....
For the preparation and standardization of NaOH with KHP im supposed to boil water for 1hr and 30 min to remove CO2
For the preparation and standardization of NaOH with KHP im supposed to boil water for 1hr and 30 min to remove CO2....the problem is that if I don't boil it for that long and (30 min) b/c of not enough time but I put the water I boiled for 1/2 hr aproximately into a NaOH bottle with a CO2 absorber and stored it there for a few days. I would assume that I would have to boil the water again...but...
