Identify the carboxylic acid chloride that might be used in a Friedel-Crafts acylation reaction to prepare each of the following acylbenzenes: (a) (b) How to prepare the following compound, starting with cyclopentene and any other reagents needed? Chlor...
I have available concentrated ammonia and 3 M3 M hydrochloric acid. The buffer capacity desired is 0.1 M0.1 M. Attempt at Solving By adding HClHCl to a solution containing ammonia, it will completely consume the strong acid. Resulting solution will contain ammonia and it's conjugate acid ...
How to prepare 1 ml of GTE buffer (50mM glucose,25mM Tris Hcl PH 8.0,10mM EDTA) for the plasmid isolation from the given stock solutions (2Mm Tris-Hcl ,0.5mM EDTA,1M glucose)? You have a 5.5 M solution of Tris buffer pH 7.9. Y...
Add reagent to change pH to the desired value. The reagent used to change pH should be fairly dilute and not alter chemical composition of the solution. Hydrochloric acid, 0.1M HCl, would be used to lower pH and sodium hydroxide, 0.1M NaOH, would be used to raise pH. Combining HCl and...

1 Brody CatesFollow Such a solution is usually prepared by diluting the HCl from a stock solution. Purchased concentrated HCl is usually 12.1 M. The question does not state how much acid to prepare so I will answer how to make one liter of 0.5 M HCl. ...
How much sodium chloride(MW = 58.44) would you need to measure out to prepare 100 ml of 1 M sodium chloride solution? What volume of a 0.193 M calcium hydroxide solution is required to neutralize 11.4 mL of a 0.330 M hydrochloric acid solution? For a lab experiment it is needed ...
