They form precipitates of Ferric hydroxide.
the sidium chloride
barium hydroxide
Formation of a precipitate is evidence of a chemical reaction.
Reaction_of_ferric_chloride_to_sodium_hydroxideBasically: FeCl3 (ferric chloride) + 3NaOH (sodium hydroxide) > Fe(OH)3 + 3NaCl (ferric hydroxide precipitate and sodium chloride, respectively)
Forms a yellow precipitate
the sidium chloride
Beryllium hydroxide
barium hydroxide
Magnesium hydroxide, a precipitate, is formed.

It forms a precipitate called sodium chloride and barium hydroxide, which both are colourless.
Forms a yellow precipitate
One such salt would be aluminum chloride since it is soluble but when reacted with ammonium hydroxide, the insoluble aluminum hydroxide forms a precipitate. Not sure what is meant by "is insoluble in excess", however.
No, they will not. Because the salt formed is Ammonium chloride, which is highly soluble in water. Only insoluble salts form a precipitate.
The chemical formula of sodium hydroxide is NaOH. The chemical formula of ammonium chloride is NH4Cl. Any reaction between these substances in water solution.
It is Iron III hydroxide (thats the brick red precipitate). It forms as well sodium chloride which is soluble in the water of the reaction and therefore you do not see.
