Why phenol does not dissolve in water when excess?
Phenol (C6H5OH) is more organic and is a covalent compound. The percentage of carbon is more compared to -OH (the polar part). Hence phenol will dissolve in organic solvents and not in water.
What happens when a base dissolve?
It increases the concentration of OH - in a solution.
What is the name for ZnH2?
Zinc hydroxide. It is base
Does talcum dissolve in vinegar?
No, Talc (Mg3Si4O10(OH)2) does not dissolve in vinegar.
How could you separate magnesium hydroxide Mg(OH)2 from alminium hydroxide Al(OH)3?
Add sodium hydroxide solution; aluminium hydroxide will dissolve but Mg(OH)2 remain.

Is ZnOH2 an acid?
Zn(OH)2 is an amphoteric compound (dual nature), with acids it behaves as a base and with bases (alkali) as an acid, Zn(OH)2 + 2HCl = ZnCl2 + 2H2O , Zn(OH)2 + 2NaOH = Na2ZnO2 + 2H2O
What acid can dissolve SiO2?
as far as i know only HF can dissolve sio2
Why does zinc hydroxide dissolve in excess dilute sodium hydroxide?
lpkjl
Which ion is excess in alkali solution?

Bases are solutions which contain an excess of?
OH- Ions
What happens when bases dissolve?
It increases the concentration of OH - in a solution.
Why ammonia dissolve in water?
There is no reason for that. It forms OH- after the reaction.
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 happens when a base dissolve?
It increases the concentration of OH - in a solution.
