RP 11 Identifying transition metals Flashcards
1
Q
How do transition metals undergo precipitation reactions
A
React with hydroxide ions to form a metal hydroxide precipitate
Cu2+ + 2OH- –> Cu(OH)2
2
Q
What can be reacted with transition metals for a precipitation reaction to occur
A
Aqueous sodium hydroxide
Ammonia
3
Q
What is the first test that can be carried out to identify transition metal ions
A
Place 10 drops each solution in test tube
Add NaOH drop by drop until excess. Record observations
Stand in beaker of hot water for 10 mins
