,THINGS I GOT WRONG IN MY EXAM
Aluminium precipitate DISSOLVES in excess sodium hydroxide
Please, please, please always check maths questions – especially % by mass
that you have added up ALL of the elements
, The melting and boiling
of a pure element or
compound are called a fi
point
Pure Mixtures do not have a
melting point and chang
substances state over a range of
temperatures (i.e. the g
and has a slanted line)
mixtures Impurities tend to lower
melting and boiling poin
the purer the compound
narrower the melting po
range
