Potassium acetate is frequently used in the preparation of plasmid DNA through the aid of alkali lysis, because potassium forms an almost insoluble precipitate together with the SDS used, and you can almost eliminate the SDS quantitatively in an elegant manner. View chapter Book 2007, Molecular ...
Buffer solution; determination of lead and iron; separating lead sulfate from other sulfates. Preparation Ammonium acetate is manufactured by neutralizing acetic acid with ammonium carbonate or by passing ammonia gas into glacial acetic acid. Acidic ammonium acetate, CH3CO2NH4.CH3CO2H[25007-86-7],...
