Place 3.0 g of salicylic acid in a 125-ml Erlenmeyer flask. Carefully add, stirring constantly, 6 mL of acetic anhydride, followed by 10 drops of concentrated sulfuric acid. Swirl the contents of the flask so that the reactants are thoroughly mixed. Stopper the flask with a one- hole cork fitted with an inverted Pasteur pipet to prevent condensation of water in the reaction flask during heating on the steam bath. Heat the flask in a boiling-water or steam bath for...

THE EMPIRICAL FORMULA OF SELECTED HYDRATES experiment PROCEDURE THIS EXPERIMENT SHOULD BE DONE IN PAIRS. 1. Available to you should be: a Büchner funnel, a rubber funnel adapter, side-arm filter flask, thick-walled rubber tubing, plastic forceps and a plastic spatula. 2. Before you turn the hotplate on, wipe the hotplate down with a damp paper towel. During this experiment you will be placing filter paper containing products directly onto the surface of the hotplate. As such, you will want to...

ALT CHEM 125 Name Determining the Ksp of Calcium Hydroxide Calcium hydroxide is an ionie solid that is sparingly soluble in water. A saturated, aqueous, solution of Ca(OH), is represented in equation form as shown below. Ca(OH)2 (5) --- Ca' (aq) + 2OH(aq) The solubility product expression describes, in mathematical terms, the equilibrium that is established between the solid substance and its dissolved ions in an aqueous system. The equilibrium expression for calcium hydroxide is shown below. Kp - [Ca][OHT...

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...
