Cations can be identified with flame tests or precipitate tests using sodium hydroxide and ammonia solutions. Anions (halide, sulfate, and carbonate ions) can be identified using precipitate tests or ...
Sodium hydroxide is added to a cylinder of aluminum nitrate, precipitating out aluminum hydroxide. When additional base is added, the precipitate dissolves. The reactions can then be reversed with the ...
Jar test-type experiments were conducted to determine the critical coagulation concentrations and critical stabilization concentrations for typical anions acting on a ${\rm Cr}({\rm OH})_{3}$ colloid ...
