If some easily oxidised substance is dissolved in water and chlorine is passed
into the liquid the substance is usually oxidised ; thus a solution of sulphur
dioxide reacts with chlorine to produce sulphur trioxide , a solution of
phosphorous oxide ...

These five elements are very easily oxidised ; when exposed to air at ordinary
temperatures the surface of the element at once becomes covered with a film of
oxide . They decompose cold water rapidly with formation of hydrogen and a ...

They are all light , soft , very easily oxidised , very ... As the combining weights of
the alkali metals increase the metals become heavier ( sodium and potassium
are exceptions ) , more positive , more easily oxidised , and more easily melted .

only sulphur , or only selenion , consists in the facts — ( 1 ) that a given mass of
one variety is changeable into exactly the same mass of another variety ; ( 2 ) that
equal masses of the different varieties when oxidised produce each exactly the ...
