To make ethyl acetate, react ethanol with ethanoic acid in the presence of concentrated sulphuric acid. Another method is by preparing industrially using the Tishchenko reaction by combining two equivalents of acetaldehyde in the presence of an alkoxide catalyst.

∙ 12y agoIf you drip H2SO4 into NaCl it will release HCl gas and produce Na2SO4. So set up a three neck round bottom loaded with NaCl and a stir bar (No solvent). Put a stopper into one of the necks, an addition funnel full of H2SO4 in the second and then a hose adapter on the third. Attach one end of the hose to the reaction flask and the other to the inlet of a bubbler loaded with more H2SO4 (This will dry the HCl gas). Attach a second hose to the outlet of the bubbler. This hose should lead to a needle or bubbling apparatus in a chilled flask of ethyl acetate. (The point is to bubble the HCl through the ethyl acetate) The ethyl acetate flask should also be vented because not all the HCl will dissolve.
Based on how much ethyl acetate you use you should be able to calculate the mass gained from the dissolved HCl. Using that gain in mass you can monitor concentration. So, keep bubbling until you hit 3M or go over 3M and dilute back down. In my experience, this isn't terribly efficient and will take quite a bit of NaCl and H2SO4, but it works!

How do you increase the solublity of loperamide hcl?
Loperamide(R) is soluble in ammonium acetate buffer (0.01 M, pH=5), diluted 0.001M HCl and methanol.
Why you used sodium acetate in osazone test?
Anhydrous sodium acetate is added to buffer the phenylhydrazine HCl so that it may function properly. Regards mawaisnawaz@hotmail.com
Why standard normality of HCl is 11.3 N?
g HCl solution = 2500 mL of HCl * 1 liter/1000 mL * 1190 g/L = 2975 g 37% solution (37 g HCl/100 grams of solution) gives you the grams of HCl: g HCl = 0.37 * 2975 g = 1100.8 g HCl Moles HCl = 1100.8/(36.46 g/mole) = 30.2 moles Therefore the molarity, which equals the normality in this case = 30.2 moles/2.5 L = 12.07 M = 12.07 N If you want to make 100 mL of a 0.1 N solution, Volume of HCl solution needed = (0.1 N * 100 mL) /12.07 N = 0.83 mL Take 0.83 mL of the 37% HCl, and dilute it with water to 100 mL.
Why add water to hcl solution?
To dilute it.
How do you make a stannous chloride solution?
you can add some pieces of pure tin or tin powder in HCl . Sn (s) + 2 HCl (aq) → SnCl2 (aq) + H2 (g)
How does one test for an acetate ion in an unknown solution?
add HCl and a vinegar smell should produce
Tris buffer as pH by HCl why not for sodium acetate?
The question is in poorly worded. I will assume the question is "why adjust the pH of Tris buffer with HCl and not Sodium Acetate?" I would assume the answer is - because sodium acetate is the conjugate base of a weak acid, and HCl is a strong acid. Also the salts you would be putting into the solution as a result would be different. I think the question is actually, "The pH of Tris is adjusted with HCl, why isn't the pH of sodium acetate adjusted with HCl?". I'm not sure of the answer exactly, but I've always assumed its because if you adjust the pH with glacial acetic acid instead of HCl, you won't introduce chloride ions.
How to make hcl from chlorine?
You cannot make HCL out from just Xhlorine. U will need Hydrogen to. Hcl is a Hydrochloric solution so u will need a method to combine Hydroger and chlorine in order to make HCL
What happens when HCl is mixed with a solution that is not a buffer solution?
If the solution is not a buffer, the HCl will react with the solution to form a product.
How do you make 60 mL of a 0.1 M HCl solution from 6.0 M HCl?
To convert make a dillute solution from a concentrated one, take the amount of moles needed for the final solution as mL of concetrated solution, and dillute with water until the desired volume is reached.
How do you prepare 0.2N HCl solution from 1.0N HCl?
Add 200 mls of the 1.0N HCl solution to a 1 liter volumetric flask. Make up to the mark with water. Standardize against a known weight of Sodium Carbonate.
How many mL of HCL do you measure to prepare a liter of 0.5N HCL?
44.5 ml HCl TAKE AND DILUTE UP TO 1000 ML WATER MAKE A 0.5 M HCl SOLUTION
How do you make 600 mL of a 1 molar solution of HCl using a 6 molar stock solution?
combine 100 mL 6 M HCl with 500 mL H2O
What is the reaction for the preparation of ethylene dibromide from ethene?
When ethyl chloride is reduced with atomic hydrogen ethane and HCl are formed, Zn + 2HCl -------> ZnCl2 + 2[H] CH3-CH2-Cl + 2[H] -----> CH3-CH3 + HCl
What is the molarity of a solution prepared by dissolving 1.56 grams of gaseous HCl in enough water to make 26.8 mL of solution?
Find moles of HCl first. 1.56 grams HCl (1mole HCl/36.458 grams) = 0.0428 moles HCl Molarity = moles of solute/volume of solution Molarity = 0.0428 moles/26.8 ml = 0.00160 milli-Molarity, or more to the point; = 1.60 X 10^-6 Molarity of HCl
Why you need to standardize HCl solution?
HCl is a gas. It's therefore very difficult to accurately weigh out the proper amount to use to make a solution of any given concentration, and as the solution sits, some HCl may escape as gas. In contrast, it's very easy to weigh out a solid base to high precision, and use a solution made from it to standardize the only-approximately-known HCl concentration.
How do you make an electrolyte solution?
