A Chemistry Question-help please??

Former MemberFormer Member Posts: 1,876,328 The Mix Honorary Guru
I dont know what level this is as its for a pharmacy BTec, but im really stuck with this question and id be very grateful for some help!!

Titanium is manufactured by heating titanium (IV) chloride with sodium;

TiCl4+Na
>Ti+NaCl

What mass of sodium is required to produce 1 tonne of titanium??

The answer is 1.22, apparently, but i need to show i can work it out.

thanks

    Something to do with atomic weights isn't it? You have to work out the values. So long ago I did Chemistry.

    tum te tum.

    The nations of the earth are nothing more than a film of dust on a weighing scale.

    first of all you need to add the right coefficients to that fomula.

    TiCl4 + 4 Na --> Ti + 4 NaCl

    every element has to appear on the left and right side of the equation. So as you can see you need 4 times the amount of sodium than TiCl4 so this reaction works. (not weight wise, but 4 times the amount of mol, or however you say that in english).

    Ti weighs 48grams per mol.
    So one ton of Titan is 20833 mol.

    Since you need 4 times the amount of Sodium you need 83333 mol Sodium, which is at 23grams per mol, 1.916 tons of Sodium.

    It might be wrong since it's late and I am overworked, but you get the idea.

    I get ya, thanks. Oops, i copied out the question, but forgot to change it because the first question was to balance it. (i did that bit)

    When i worked it out i was getting 1.9 aswell, but we've already been told that its 1.22.

    confused!!

    I've got an A level in chemistry but Im lost. I havn't done any calculations like that for years and I'm hungover.

    Same goes. Science was one of my weak points. My brain is just not geared up to cope :blush:
