To prepare 1 liter of this solution, dissolve 294.42 g potassium acetate in 100 ml water, and add glacial acetic acid until a pH of 4.6 is reached. This will require about 40-50% of the final volume to be acetic acid.Potassium acetate is frequently used in the preparation of plasmid DNA through the aid of .

60 mL of 5 M potassium acetate, 11.5 mL glacial acetic acid, 28.5 mL double-distilled H2O. The resulting solution is 3 M acetate and 5 M potassium and has a pH of about 4.8. Store at room temperature, and do not autoclave Boiling Lysis Method (reference here) This procedure is quick and reliable for preparing plasmid from small volume cultures.

You need to make an aqueous solution of 0.228 M potassium hydroxide for an experiment in lab, using a 125 ml volumetric flask. How much solid potassium hydroxide should you add? grams How many milliliters of an aqueous solution of 0.248 M copper(IT) bromide is needed to obtain 9.07 grams of the salt? ml In the laboratory you dissolve 24.4 g of calcium acetate in a .I don't ahaha. When you autoclave them you are just making them dirtier. All water vapour going everywhere and yes I know it should be distilled water but have you ever smelled an autoclave? add. I think a good way of understanding why people do certain things is seeing how flawed you are. Everyone is flawed and everyone does stupid things.I autoclave 1 M Imidazole at pH 8, but nothing else. Some buffers decompose in the autoclave. After about 2 months, both MES and MOPS buffer turn yellow at room temperature by oxidation. The same thing happens in the autoclave. Yellow MES and MOPS is an oxidized form of the buffers. Nobody knows what it is. Nobody cares. The pH remains the same .
