The reactivity series Flashcards
what is the reactivity series
lists metals in order of their reactivity towards other substances
how is metals reactivity determined
how easily they lose electrons - forming positive ions. the higher up the reactivity series a metal is, the more easily they form positive ions
what happens when metals react with water or acid
they lose electrons and form positive ions
how do metals react with acids tells you about their reactivity
some metals react with acids to produce a salt and hydrogen gas
acid + metal – salt + hydrogen
how else can you measure the reactivity of metals
measuring the temperature change of the reaction with an acid or water over a set time period. the more reactive the metal the greater the temperature change should be
what is the word equation of metals reacting with water
metal + water – metal hydroxide + hydrogen
