Q

What can be observed when a metal and an acid react together?

A

· Bubbles/ effervescence (caused by the production of hydrogen gas)
· Formation of a solution (if the salt produced is soluble

Are H+ ions reduced or neutralised?

A

They gain electrons from the metal and are therefore reduced

Q

Hydrogen carbonate + acid = ?

A

Salt + water + carbon dioxide

17
Q

What’s the hydrogen carbonate ion

A

HCO3-

18
Q

What’s a displacement reaction

A

One element (the more reactive) replaces element in a compound

19
Q

What’s a precipitation reaction

A

A reaction in which an insoluble solid is produced when two solutions are mixed

20
Q

How can you test for carbonates?

A

· Adding dilute acid to a solution containing carbonate ions will cause fizzing due to the production of CO2 gas
· The gas produced will turn limewater cloudly

21
Q

How can you test for sulfates?

A

· Most sulfates are soluble in water. · Barium sulfate however is very insoluble. Its formation produces a white precipitate

· By adding barium chlorude or barium nitrate to a solution, we can identify if a sulfate is present

22
Q

What’s the ionic equation for the reaction

A

Ba2+ (aq) + SO42- (aq) –> BaSO4 (s)

23
Q

How can you test for halides?

A

Aqueous halide ions react with aqueous solved ions to form precipitates of different colours

By adding silver nitrate (and nitric acid) to a solution, we can identify if a halide is present
