Al(OH)3 (s) + OH- (aq) -------> [Al(OH)4]- (aq)
Aluminium hydroxide undergoes further reaction with hydroxide ion to from a complex ion, which is of course, soluble in water.
Some other metal hydroxides also have similar reaction, like zinc hydroxide, and lead (II) hydroxide.

What is the balance equation for chemical reaction of aluminium with sodium hydroxide?
2 Al + 6 H2O > 2 Al(OH)3 + 3 H2 Al(OH)3 + NaOH > Na+ + [Al(OH)4]- __________________________________________________________________ 6H2O(l)+2Al(s)+2NaOH(aq)--------------- 2NaAl(OH)4(aq)+3H2(g)
What is formed when Excess of sodium hydroxide react with zinc?
This reaction is to be carried out with Sodium hydroxide dissolved in water and Zinc oxide. The product is Sodium Tetrahydroxidozincate(2-) or Simply Sodium Zincate.ZnO + 2 NaOH + H2O ----> Na2Zn(OH)4
Why zinc hydroxide is soluble in excess of sodium hydroxide solution?
Zinc hydroxide Zn(OH)2 is an inorganic chemical compound. It also occurs naturally as 3 rare minerals: wülfingite (orthorhombic), ashoverite and sweetite (both tetragonal).Like the hydroxides of other metals, such as lead, aluminium, beryllium, tin and chromium, zinc hydroxide (and zinc oxide), is amphoteric. Thus it will dissolve readily in a dilute solution of a strong acid, such as HCl, and also in a solution of an alkali such as sodium hydroxide.It can be prepared by adding sodium hydroxide solution, but not in excess, to a solution of any zinc salt. A white precipitate will be seen: Zn2+ + 2OH- → Zn(OH)2.If excess sodium hydroxide is added, the precipitate of zinc hydroxide will dissolve, forming a colorless solution of zincate ion: Zn(OH)2 + 2OH- → Zn(OH)42-. This property can be used as a test for zinc ions in solution, but it is not exclusive, since aluminum and lead compounds behave in a very similar manner. Unlike the hydroxides of aluminum and lead, zinc hydroxide also dissolves in aqueous ammonia to form a colourless, water-soluble ammine complexThe reason that the zinc hydroxide will dissolve is because the ion is normally surrounded by water ligands; when excess sodium hydroxide is added to the solution the hydroxide ions will reduce the complex to a -2 charge and make it soluble. When excess ammonia is added, it sets up an equilibirum which provides hydroxide ions; the formation of hydroxide ions causes a similar reaction as sodium hydroxide and creates a +2 charged complex with a co-ordination number of 4 with the ammonia ligands - this makes the complex soluble so that it dissolves
What are the products of aluminum oxide and sodium hydroxide?
Since aluminium oxide is an amphoteric oxide, it does react with the alkali sodium hydroxide in an aqueous medium. It is an acid base reaction.
Why sodium Hydroxide Solution Cannot Be Kept In Aluminium Containers?
Sodium Hydroxide in contact with some metals ( Aluminium , Magnesium , Zinc ) reacts to produce flammable and potentially explosive Hydrgen Gas. Aluminium is actually a very reactive metal that is unusual as it has layer of oxide ( Al2O3 ) on the surface. This oxide is soluble in base forming an aluminate exposing the Aluminium surface which reacts.
If solid sodium hydroxide were added to neutralize the HCl would this reverse the reaction and cause the sodium chloride to redissolve?
No, adding solid sodium hydroxide to neutralize hydrochloric acid (HCl) would not cause sodium chloride to redissolve. The reaction between sodium hydroxide and hydrochloric acid forms water and sodium chloride, which remains in its dissolved form. The addition of solid sodium hydroxide would simply further neutralize the acid and increase the concentration of the resulting sodium chloride solution.
What is the balance equation for chemical reaction of aluminium with sodium hydroxide?
2 Al + 6 H2O > 2 Al(OH)3 + 3 H2 Al(OH)3 + NaOH > Na+ + [Al(OH)4]- __________________________________________________________________ 6H2O(l)+2Al(s)+2NaOH(aq)--------------- 2NaAl(OH)4(aq)+3H2(g)
Describe the test for aluminium ions?
Test: Add aqueus sodium carbonate solution, then warm it. Observation: Formation of white precipitate. Deduction: The presence of aluminum ions, Al3+ Or Test: Observation: Add aqueous sodium hydroxide White precipitate occur Add aqueous sodium hydroxide (excess) & warm White precipitate solute Test with red litmus paper Changes red - blue Deduction: The presence of aluminum ions, Al3+
What is redissolved in excess?
Aluminium hydroxide = Al(OH)3 , and Zinc hydroxide = Zn(OH)2 , is redissolved in excess Sodium hydroxide = NaOH (in water solution) : Al(OH)3 + NaOH + H2O ----> NaAl(OH)4 Zn(OH)2 + NaOH + H2O ----> Na2Zn(OH)4
What is the balanced equation for zinc hydroxide react with excess sodium hydroxide?
There is no reaction between zinc hydroxide and sodium hydroxide.
What is the predicted effect on the reaction of zinc nitrate and excess sodium hydroxide?
The reaction of zinc nitrate and excess sodium hydroxide begins with precipitation of zinc hydroxide ( Zn(OH)2 ), followed by dissolvement after adding excess sodium hydroxide ( 2 OH- ) to formation of zinc aat-ions ( [Zn(OH)4]2- )
. If solid sodium hydroxide were added to neutralize the HCl would this reverse the reaction and cause the sodium chloride to redissolve?
No, adding solid sodium hydroxide to neutralize the hydrochloric acid would not cause sodium chloride to redissolve. The reaction between hydrochloric acid and sodium hydroxide forms water and sodium chloride, which would remain as a dissolved salt in the solution. The addition of more sodium hydroxide would further neutralize the acid but not reverse the formation of sodium chloride.
What reacts with water to make hydrogen gas?
Aluminium foil, sodium hydroxide
Which gas is liberated when an alkaline solution of sodium nitrate is warmed with aluminium?
Aluminium react with sodium hydroxide releasing hydrogen.Sodium nitrate is decomposed by heating releasing nitrogen dioxide.
What gas produced when aqueous sodium nitrate is warmed with aqueous sodium hydroxide and aluminium foil?
The reaction between aqueous sodium nitrate, sodium hydroxide, and aluminum foil produces hydrogen gas. This is because aluminum reduces sodium ions to sodium metal, which releases hydrogen gas in the presence of water and sodium hydroxide.
What is formed when Excess of sodium hydroxide react with zinc?
This reaction is to be carried out with Sodium hydroxide dissolved in water and Zinc oxide. The product is Sodium Tetrahydroxidozincate(2-) or Simply Sodium Zincate.ZnO + 2 NaOH + H2O ----> Na2Zn(OH)4
Will aluminium react with sodium bicarbonate?
Aluminum will not react with sodium bicarbonate under normal conditions. Aluminum is a relatively inert metal and does not easily undergo chemical reactions with weak bases such as sodium bicarbonate.
