Because proteins are relatively insoluble at mid-range pH of around 4.5. The pH affects the charge of the protein causing a precipitate to for.
No, ammonium hydroxide and hydrochloric acid will not form a precipitate when mixed together. The reaction between them will result in the formation of ammonium chloride, which will remain dissolved in the solution.
the solution is not allowed to be chilled for it recrystallize
Boric acid is not meant to be chilled because it can crystallize and precipitate out of solution at low temperatures, which can affect its efficacy and stability. It is recommended to store boric acid solution at room temperature to keep it in liquid form and fully effective.
The precipitate of salicylic acid dissolves in excess sulphuric acid due to the formation of a complex between salicylic acid and sulphuric acid, which increases the solubility of the precipitate. This reaction results in the formation of a colorless solution, as the salicylic acid is converted into its conjugate base form.
No, for a precipitate to form, at least one product must be insoluble in the solution. When two soluble reactants combine, they can form an insoluble product known as a precipitate, which will then separate out of the solution.
No, hydrochloric acid does not form a precipitate with cupric sulfate solution because chloride ions remain in solution and do not react with copper ions to form a solid product.
No, ammonium hydroxide and hydrochloric acid will not form a precipitate when mixed together. The reaction between them will result in the formation of ammonium chloride, which will remain dissolved in the solution.

A chemical substance that will form a precipitate with NH4Cl solution is AgNO3, resulting in the formation of a white precipitate of AgCl. With K2CrO4 solution, Pb(NO3)2 will form a yellow precipitate of PbCrO4.
When barium hydroxide solution is mixed with sulfuric acid, a white precipitate of barium sulfate is formed due to a double displacement reaction. Barium sulfate is insoluble in water and thus forms a solid precipitate. This reaction is used in chemistry labs to test for the presence of sulfate ions.
Solid solution
AlCl3 can precipitate with compounds that contain chloride ions, such as NaCl, KCl, or HCl, to form insoluble AlCl3 complexes. This reaction can be used for the precipitation of aluminum ions from a solution.
Common methods used to purify proteins include chromatography, electrophoresis, and precipitation. Chromatography separates proteins based on their size, charge, or affinity for a specific ligand. Electrophoresis separates proteins based on their charge and size. Precipitation involves adding a reagent to the protein solution to cause the proteins to come out of solution and form a solid precipitate, which can then be separated from the rest of the solution.
