When ammonia is passed through an aluminum sulfate solution, it reacts to form aluminum hydroxide, which precipitates out of the solution. This reaction occurs because ammonia acts as a base, raising the pH and causing aluminum ions to hydrolyze and form insoluble aluminum hydroxide. The overall process can be represented by the reaction: ( \text{Al}_2(\text{SO}_4)_3 + 6 \text{NH}_3 + 6 \text{H}_2\text{O} \rightarrow 2 \text{Al(OH)}_3 \downarrow + 3 \text{(NH}_4\text{)}_2\text{SO}_4 ). The aluminum hydroxide precipitate can then be filtered out from the solution.
You can obtain the ferric sulphate - Fe2(SO4)3; because the ferrous sulphate react as a reducing agent.
When red litmus paper is dipped in ammonia, it turns blue. Ammonia is a basic (alkaline) substance, and the change in color indicates the presence of a base. This reaction happens because the ammonia raises the pH of the solution, causing the red litmus paper to change color.
There would be no reaction because copper is a less reactive metal than iron. Refer to the related link for an activity series of metals.
Hi there, I am not very sure what the coating is called but i think it is iron oxide. lolxx
sulphate
well, ammonia is a very hot country and there is really loads of stuff there :0
A precipitate is formed which has a light blue colour. After shaking, the precipitate re-dissolves forming a dark blue solution.
Answer plc urgent
Sh!t happens.
When Ammonia solution is added to Copper sulphate, at first a precipitate of Copper hydroxide is formed. If excess ammonia is added, finally a deep bluish solution of Tetraamine Copper(II) Sulfate is formed
When copper(III) sulfate solution reacts with ammonia, a dark blue precipitate of copper(II) hydroxide is formed. This happens due to the displacement of the ammonia ligands by hydroxide ions in solution, resulting in the precipitation of copper(II) hydroxide. The reaction can be represented as CuSO4 + 2NH3 + 2H2O -> Cu(OH)2 + (NH4)2SO4.
ammonia should release on heating.
i think that it would be displaced .... wont it?
the solution turns green and the nails develop a brown deposit which is copper. the iron displaces the copper in the copper sulphate solution. This is because iron is more reactive than copper.
Nothing. Gold is a noble metal- it is not displaced by iron.
When iron nails are placed in copper sulphate solution, a displacement reaction occurs where iron replaces copper in the solution to form iron sulphate and copper metal. The word equations for the reactions involved are: Iron (s) + Copper sulphate (aq) -> Iron sulphate (aq) + Copper (s)
