- - - - K and Na are very dangerous and react EXPLOSIVELY with acids
    - - Sulfuric acid
        
        rapid bubbling, splint goes 'pop', metal dissolves
        
        Mg + H2SO4 ---> MgSO4 + H2
      - Hydrochloric acid
        
        Dissolves quickly, gets hot, splint goes 'pop', colourless solution left
        
        Mg + 2HCl --> MgCl2 + H2
    - - Sulfuric acid
        
        slow reaction, small bubbles seen
        
        Fe + H2SO4 --> FeSO4 + H2
      - Hydrochloric acid
        
        very slow bubbling
        
        Fe + 2HCl --> FeCl2 + h2
    - - Sulfuric acid
        
        metal dissolves forming a colourless solution, gas given off slowly
        
        Zn + H2SO4 ---> ZNSO4 + H2
      - Hydrochloric acid
        
        bubbles given off, metal dissolves slowly
        
        Zn + 2HCl ---> ZnCl + H2
