Why does aluminium hydroxide redissolve in excess sodium hydroxide?
Jockeyman1995
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)
Why can't we store sodium hydroxide solution in aluminium containers?
Sodium hydroxide reacts with aluminum, corroding the metal and producing hihgly flammable hydrogen gas.
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.
Is there any reaction between benzalkonium chloride and aluminium?
Negative. Aluminium will react with sodium hydroxide or hydrochloric acid. Trying to make a works bomb?
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.
Will aluminium react with sodium bicarbonate?
Aluminium doesn't react with sodium bicarbonate.Aluminium react with sodium 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)
Why do the solid sodium hydroxide and aluminium powder not react when stored in a sealed container?
Sodium hydroxide must be dissociated in water.
Why does zinc hydroxide dissolve in excess dilute sodium hydroxide?

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 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- )
What gas produced when aqueous sodium nitrate is warmed with aqueous sodium hydroxide and aluminium foil?
Ammonia
What is the balanced equation for zinc hydroxide react with excess sodium hydroxide?
There is no reaction , because of the Common Ion Effect. The Common Ion is the Hydroxide.
What reacts with water to make hydrogen gas?
Aluminium foil, sodium hydroxide
Why can't we store sodium hydroxide solution in aluminium containers?
Sodium hydroxide reacts with aluminum, corroding the metal and producing hihgly flammable hydrogen gas.
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+
