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 sol

fredd [130]

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,
