Reactions Of Acids Flashcards
when is a salt formed
- during a neutralisation reaction
- a reaction between an acid an a base
what are salts
ionic compounds
what kinds of salts do hydrochloric, sulfuric and nitric acid make
- chloride salts
- sulfuric salts
- nitrate salts
what does acid + metal oxide produce with an example
- salt + water
- 2HCL + CuO = CuCl + H2O
- hydrochloric acid + copper oxide = copper chloride + water
what does an acid + metal hydroxide produce with an example
- salt + water
- H2SO4 + Zn(OH)2 = ZnSO4 + 2H2O
- sulfuric acid + zinc hydroxide = zinc sulfate + water
what does an acid + metal produce with an example
- salt + hydrogen
- 2HCL + Mg = MgCL2 + H2
- hydrochloric acid + magnesium = magnesium chloride + hydrogen
how can you test for hydrogen and what is the result if it is present
- using a lighted splint
- hydrogen makes a squeaky pop with the lighted splint
- noise comes from hydrogen burning with the oxygen in the air to form water
what does an acid + metal carbonate produce with examples
- salt + water + carbon dioxide
- 2HNO3 + ZnCO3 = Zn(NO3)2 + H20 + CO2
- nitric acid + zinc carbonate = zinc nitrate + water + carbon dioxide
what is the test for carbon dioxide and what is the result if it is present
- by bubbling it through limewater
- limewater will turn cloudy if CO2 is present
what kind of reaction is H2SO4 + ZnO = ZnSO4 + H20
acid + metal oxide = salt + water
what kind of reaction is HNO3 + KOH = KNO3 + H20
acid + metal hydroxide = salt + water
what kind of reaction is H2SO4 + Mg = mGSO4 + H2
acid + metal = salt + hydrogen
what kind of reaction is 2HCl + NaCO3 = 2NaCl + H2O + CO2
acid + metal carbonate = salt + water + carbon dioxide
what are the symbols for hydrochloric acid, sulfuric acid and nitric acid
- HCl
- H2SO4
- HNO3
