3. Deionized water is added to the chlorination product obtained in step 2. The mixture is heated to 80-90°C, and a sodium hydroxide solution is added dropwise to adjust the pH of the system to 2-2.3. After 4-6 hours of reaction, concentrated hydrochloric acid is added dropwise to adj...
(2) After the above reaction is completed, cool to 60-80℃ and slowly add hydrochloric acid solution to the three-necked flask while stirring. After complete addition, continue stirring for 30-50 minutes. After the reaction is finished, cool to room temperature, filter the precipitate, dissolve...
As part of chemistry class, you may have to identify unlabeled solutions. If you have a solution you suspect may be hydrochloric acid but don't know for sure, the quickest way to test uses silver nitrate solution. The test is also a good introduction to precipitation, where an insoluble so...
If instead, we slowly add the nitric acid to the hydrochloric acid, the reaction proceeds gently. Excess heat is allowed to dissipate, and toxic gases evolve gradually. The evolution of toxic gasses is also why we never store aqua regia and especially don’t prepare it in a sealed receptacle...

How to prepare hydrogen gas For the decomposition of 5.3 mol of N2H2 into ammonia and nitrogen, how many moles of ammonia form? Given the Haber process: N2(g) + 3H2(g) to 2NH3(g). How many liters of NH3 can be produced at a temperature of 27 degrees Celsius and a pressure of...
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 ...
5M hydrochloric acid Carbon Dioxide Gas Preparation Add 5M hydrochloric acid to 5g-10g marble chips. Carbon dioxide gas is released by the chemical reaction. Collect the carbon dioxide from the upward displacement of air in a hood. Carbon dioxide is about 60% denser than air, so it will fill...
Plenty of protein, plenty of vegetables. It is fine to eat starchy carbs if weight loss isn’t an issue, since evenings are wind down times. Protein and vegetables do not equate to boring or complex. They can be extremely quick to prepare, eg lamb chops with a little rosemary sprinkled ...
How could you prepare the depicted ester using the reaction of an acid chloride with an alcohol? Cyclohexyl acetate 1. Discuss the reaction mechanism for the reduction of a nitro- group using tin and hydrochloric acid. What intermediates are involved? 2...
