HOW DO ACIDS AND BASES REACT WITH METALS?
When an acid combines with metal it forms salt and release hydrogen gas
Metal + acid – metal salt + H2
2Na + H2Co3 – Na2Co3 + H2
When a base combine with metal it forms metal salt / base and release hydrogen gas
Base + metal – base/metals/salt + H2
2NaoH + Zn – Na2ZnO3 + H2 (sodium Zincates)
Base reacts only with zinc and aluminum
How do metal carbonate and hydrogen carbonate react with acids to give a corresponding salt, carbon dioxide and water?
All metal carbonates and hydrogen carbonate react with acids to give a corresponding salt, carbon dioxide and water
Metal carbonate / metal hydrogen carbonate + acid – salt +CO2 + H2O
Na2CO3 + 2HCl – 2Nacl + H2O + CO2
NaHCo2 + Hcl – H2O + H2O + CO2
Limestone, chalk and marble are different form of calcium carbonate
How do acids and bases react with each other?
When acids react with bases it forms salt and water
Acid + base – salt + water
NaOH + Hcl – Nacl + H2O
The reaction between an acid and a base to give salt and water is called neutralization reaction
In this reaction the effect of a base is nullified by and acid and vice-Vera
Reaction of metallic oxides with acids
When acid reacts with metallic oxide then it forms corresponding salt and water
Metal oxide + acid – salt + water
CuO + H2SO4 – CuSO4 + H2O
Acids react with metallic oxides to give salt and water similar to the reaction acid and base So, metallic oxides are called basic oxide
Reaction of a Non – metallic oxide with base
When base reacts with non-metallic oxide then it forms salt and water
Non – metallic oxide + base – salt + water
Ca (OH)2 + CO2 – CaCO3 + H2O
This reaction is like acid and base So, non – metallic oxides are acidic in nature
What do all acids and all bases have in common?
All acids have H+ ions in common and all bases have OH- ions in common
What happens to an acid or a base in a water solution?
When an acid is mixed in water it dissociates H+ ions
Hcl + H2O – H3O+ +cl-
Hydrogen ions cannot exist alone so, it combines with water molecules and forms H3O+ ions called hydronium
When a base is mixed with water it dissociate OH- ions
NaOH (s) H2O Na + (aq) + OH- (aq)
KOH (s) H2O K + (aq) + OH- (aq)
When an acid combines with metal it forms salt and release hydrogen gas
Metal + acid – metal salt + H2
2Na + H2Co3 – Na2Co3 + H2
When a base combine with metal it forms metal salt / base and release hydrogen gas
Base + metal – base/metals/salt + H2
2NaoH + Zn – Na2ZnO3 + H2 (sodium Zincates)
Base reacts only with zinc and aluminum

Acids will react with reactive metals,such as magnesium and zinc,to make out salt and hydrogen.the hydrogen causes bubbling during the reaction.It can be detected using a light splint,which causes the gases to burn with a squeaky pop.
when the burning matchstick or candle burns with a pop sound it confirms the evoulution of hydrogen gas.Copper does not react even with concentrated hydrochloric acid.However,copper react with sulphuric acid. Non-metals generally do not react with acids.
Acid-Base reactions.When an acid and a base are placed together,they react to nuetralize the acid and base properties,producing a salt.theH(+) cation of the acid combines with the OH(-) anion of the base to form water.The compound formed by the cation of the base and the anion of the acid is called salt.
