Hahaha,,,, today,, we did a experiment,,,
which is lab 4C  FORMULA OF A HYDRATE.

The procedure was:
First,,, Wear your safety GOGGLES!!
 Then set up the pipestem triangle, iron ring, stsand and bunsen burner....
Heat the crucible with busen burner for around 3 min,, to make sure it is dry,,,,,,

-Let crucible cool down and measure the mass of it.

-put the given hydrate inside the crucible and record the mass.

_heat the crucible(with hydrate) until the buttom of crucible is dull red,,, for about five min

-after that,, let it cool down for approximately five min,,,, and record down the mass of it

-to make sure all water is driven off,,,, reheat it for another five min

-cool it down for another five min again and record the mass

-lastly,,,,  drops a few water to the contents of the crucible and see what happen!! XDD
