C6 - Metals And Acids Flashcards
What is the reactivity series?
Magnesium Aluminium Zinc Iron Hydrogen Copper
What is the formula for a reaction between an acid and metal?
Acid + metal -> hydrogen + salt
When dilute acid is added, what is expected of the reactions?
The reaction rate is indicated by the speed of the hydrogen bubbles given off. Copper is less reactive than hydrogen so will not produce a squeaky pop in the burning splint test which indicates hydrogen.
The more reactive the metals, the fast the reaction.
Sodium is explosive.
Hydrochloric acid always produces …
Chloride salts which are soluble (aq), excluding silver and lead chloride.
Sulfuric acid always produces…
Sulfate salts which are soluble (aq), excluding lead sulfate.
Give a symbol equation for zinc and hydrochloric acid…
Zn (s) + 2HCl (aq) -> ZnCl2 (aq) + H2
