How do transition metals undergo precipitation reactions?

Answer 1

They react with hydroxide ions to form a metal hydroxide precipitate.
I.e. Cu2+ (aq) + 2OH- (aq) —> Cu(OH)2 (s)

Question 2

What can be reacted to transition metals for a precipitation reaction to occur?

Answer 2

• aqueous sodium hydroxide
• ammonia
