A double replacement reaction takes place when aluminum sulfate reacts with ammonium hydroxide; the precipitate will be aluminum hydroxide (the ammonium sulfate will remain in solution, and we're assuming the reactants were already in aqueous solution.) Most metallic hydroxides are insoluble. The balanced equation for this reaction, showing the appropriate states of matter is:
Al2(SO4)3(aq) + 6NH4OH(aq) --> 3(NH4)2SO4(aq) + 2Al(OH)3(s)
After this reaction any precipitate is formed.
No b/c ALL ammonium (NH4+) and sodium (Na+) compounds are soluble so even if you write a double replacement reaction, the products will still each be soluble so there is actually no reaction.
Copper hydroxide is the precipitate.
calcium hydroxide
light blue color
The chemical reaction is:2 NH4Cl + Ca(OH)2 = 2 NH4OH + CaCl2
The chemical reaction is:C6H5COOH + NH4OH = C6H5COONH4 + H2O
A precipitate
I guess it is called as NH4OH
Decomposition
Copper hydroxide is the precipitate.
(Don't forget to balance it) The precipitate here has to be 2NaCl, as Ca(CO3)2 technically dissolves.
The chemical equation is:3 NaOH + FeBr3 = 3 NaBr + Fe(OH)3
calcium hydroxide

These compounds will not react. They both contain the same anion, and thus there can be no reaction between them. Consequently, the reactants will remain unchanged.
The chemical reaction is:2 NH4Cl + Ca(OH)2 = 2 NH4OH + CaCl2
The chemical reaction is:C6H5COOH + NH4OH = C6H5COONH4 + H2O
when 8-hydroxyquinoline and aluminum reacts a yellow ppt is formed( aluminum-8-hydroxyquinolate) .....but bot sure bout d ammonium acetate. I kno the ammonium acetate helps the helps the precipitate to form.....hope someone can fill the blanks...
