Which one reacts first when the hydrogen ion encounters both hydroxide and metaaluminate ions? -_-.sorry! It's magnesium hydroxide.
Reaction with OH first
Because the ionization difficulty of H2O is greater than that of meta-aluminate, the binding capacity of H2O to H ion is greater than that of meta-aluminate ion.
Hope to adopt

THE REACTION OF ALUMINIUM IONS WITH HYDROXYL IONS First, the ion equation of OH- is added dropwise to the Al3+ solution; Secondly, the ion equation of Al3+ is added to OH- solution dropwise. THE REACTION OF ALUMINIUM IONS WITH HYDROXYL IONS First, the ion equation of OH- is added dropwise to the Al3+ solution; Secondly, the ion equation of Al3+ is added to OH- solution dropwise;
As shown in the figure
The first kind: aluminum ion solution is excessive, so aluminum hydroxide precipitation is formed;
The second kind: excessive hydroxide solution, aluminum hydroxide precipitation and hydroxide reaction to form metaluminate ion
This is mainly due to the amphoteric nature of aluminum hydroxide, i.e. acidic and basic.
Want to adopt, if do not understand, can ask.
As shown in the figure
The first kind: aluminum ion solution is excessive, so aluminum hydroxide precipitation is formed;
The second is that if the hydroxide solution is excessive, the generated aluminum hydroxide precipitation will react with the hydroxide to form aluminate ions
This is mainly due to the amphoteric nature of aluminum hydroxide, i.e. acidic and basic.
Please accept, if you do not understand, can ask.
