The number of moles of water of crystallisatin in hydrated sodium carbonate?!!?
Help! I have to do a written piece on this experiment and does anyone have any background information about this because it is needed urgently!
Also, does anyone know what the graph axis would be for when I plot my results.is it like moles/mass or what?
Thanks!
Answers:
To find out the number of moles of water of crystallisation are in sodium carbonate crystals can be done in two ways. Either disssolving a known mass in a measured amount of water and titrating (finding how much of the solution will neutralise a standard solution of an acid) the solution to find the mass of sodium carbonate in the weighed sample. Or by heating a weighed sample and then re-weighing the sample. This heating and reweighing are repeated until there is no further loss in mass. Neither of these methods require the drawing of a graph. With either experiment the answer will be approximately 10 and you round the answer up to the nearest whole number.

I suggest you post the whole question, as you haven't given enough information above to calculate anything.
Take a deep breath and read it again, slowly!
ten.it is also called as deca hydrated sodium carbonate..or commonly as the washing soda..
upo heating it looses 9 moles of h20 of crystallisation to become monohydrated which upon further heating becomes unhydrated
Na2CO3 comes with various hydration states: 10 and 1 hydrates being the most common, beside anhydrous, too.

What is the formula for n!?
if i tickled you would you giggle?
what is millivolt drop test? how is it performed?
Do invitrogen restriction enzymes need BSA?
Is resonating the same as vibrating or oscillating?
what is the formal potential of the half reation Fe2+ to Fe3+ + e- and Ce4+ + e- to Ce3+?
why is there no recent evidence of evolution?
is it the same where you live?
