If NaOH is added to 0.010 M Al3+, which will be the predominant species at equilibrium: Al(OH)3 or Al(OH)- 4 ? The pH of the solution is 14.00. [Kf for Al(OH) - 4 = 2.0 1033.]

Sagot :

Answer:

Al(OH)- 4,

Explanation:

NaOH  added to 0.010 M Al3+

The predominant species at equilibrium will be = Al(OH)- 4,  and this because sodium hydroxide ( NaOH ) is a base will readily form a stable complex ion with aluminum ion like ( Al( OH ) - 4 . also the higher the Kf value the more stable the complex ion becomes and the more soluble  Al(OH)3 becomes

hence the predominant species at equilibrium is : Al(OH)- 4,
