Reacting Metals With Acid Flashcards
Word equation for metal+acid
Metal+acid-> salt + hydrogen
What is usually produced when a metal reacts with an acid
Hydrogen gas and salt
What metals SHOULD NOT be put in acid
Potassium,sodium,lithium because they are so explosive
What would you expect would happen if you react aluminium with water and acid
Aluminium should react with acid and water quite fast as it is just below magnesium on reactivity series. A gas should be given off, especially obvious with acid
What ACTUALLY do you observe when aluminium is reacted with acid and water
In acid nothing happens for at least 5 minutes. Then bubbles of gas appeared and the aluminium turned dark grey.
Why was this reaction with aluminium surprising
Aluminium is high up on the reactivity series but it took quite a while for the aluminium to react with acid
Why does aluminium resist corrosion
Aluminium resists corrosion as it forms a protective oxide layer on its surface and this protects the aluminium
What is aluminium widely used for
Aluminium is widely used outside as greenhouse metal frames
