What is the general equation for a reaction between metals and acids? What type of reaction is this?
Metal + acid → salt + hydrogen
Redox reaction, also a displacement reaction.
Which metals in the reactivity series will react with acid?
Those above hydrogen.
What is the general equation for a neutralization reaction?
base + acid → salt + water
What is the general equation for the reaction between metal carbonate and acid?
metal carbonate + acid → salt + water + carbon dioxide
What is the general equation for the reaction between metal oxides and acids?
metal oxide + acid → a salt + water
What is a redox reaction?
A reaction where both oxidation and reduction occurs.
Explain in terms of gain or loss of electrons which species has been oxidized and which species has been reduced when magnesium reacts with hydrochloric acid.
Magnesium has lost electrons and thus has been oxidized (Mg to Mg2+).
The hydrogen in HCl has gained electrons and thus has been reduced (H+ to H2).
