Question

Starting with rutile ( $\mathrm{TiO}_2$ ), explain how you would obtain pure titanium metal. (Hint: First convert $\mathrm{TiO}_2$ to $\mathrm{TiCl}_4$. Next, reduce $\mathrm{TiCl}_4$ with Mg . Look up physical properties of $\mathrm{TiCl}_4, \mathrm{Mg}$, and $\mathrm{MgCl}_2$ in a chemistry handbook.)

Starting with rutile (TiO_), explain how you would obtain pure titanium metal. (Hint: First convert $\mathrm{Ti} \mathrm{O}_{2}$ to TiCl_t. Next, reduce TiCl_ with Mg. Look up physical properties of $\mathrm{TiCl}_{4}, \mathrm{Mg},$ and $\mathrm{MgCl}_{2}$ in a chemistry handbook.)

titanium-is-produced-from-its-principal-ore-rutile-mathrmtio_2s-by-the-two-step-process-described-by

Titanium is produced from its principal ore, rutile, $\mathrm{TiO}_{2}(s)$, by the two-step process described by (1) $\mathrm{TiO}_{2}(s)+2 \mathrm{Cl}_{2}(g)+2 \mathrm{C}(s) \rightarrow$ $$ \mathrm{TiCl}_{4}(g)+2 \mathrm{CO}(g) $$ (2) $\mathrm{TiCl}_{4}(g)+2 \mathrm{Mg}(s) \rightarrow \mathrm{Ti}(s)+2 \mathrm{MgCl}_{2}(s)$ How many kilograms of titanium can be produced from $4.10 \times 10^{3}$ kilograms of $\mathrm{TiO}_{2}(s) ?$

a-titanium-ore-contains-rutile-leftmathrmtio_2right-plus-some-iron-oxide-and-silica-when-it-is-heate

A titanium ore contains rutile $\left(\mathrm{TiO}_{2}\right)$ plus some iron oxide and silica. When it is heated with carbon in the presence of chlorine, titanium tetrachloride, $\mathrm{TiCl}_{4},$ is formed. $$ \mathrm{TiO}_{2}(s)+\mathrm{C}(s)+2 \mathrm{Cl}_{2}(g) \longrightarrow \mathrm{TiCl}_{4}(g)+\mathrm{CO}_{2}(g) $$ Titanium tetrachloride, a liquid, can be distilled from the mixture. If $35.4 \mathrm{~g}$ of titanium tetrachloride is recovered from $18.1 \mathrm{~g}$ of crude ore, what is the mass percentage of $\mathrm{TiO}_{2}$ in the ore (assuming all $\mathrm{TiO}_{2}$ reacts)?

00:01 18 from chapter 23 and it's asking how do we obtain pure titanium dioxide? so the first thing i want to do the first step, i'm going to take titanium deoxy, so t -i -o -2, and react that with hydrochloric acid.
00:35 This is going to give us a titanium, tetrachloride, and another product of water.
00:55 Now we gotta balance this.
01:05 And when you balance this, it's going to put a four in front of hydrochloric acid.
01:13 You have four chlorides, and i'm going to put a two in front of the water.
01:19 Okay.
01:20 Next step we have is to try to find titanium even further...
