Titanium is a transition metal used in many alloys because it is extremely strong and lightweight. titanium tetrachloride (ticl4) is extracted from titanium oxide using chlorine and coke (carbon). if you begin with 1.25 mol tio2, what mass of cl2 gas is needed

Following reaction is involved in above question:

TiO2 + 2Cl2 → TiCl4 + O2

(1 mole) (2 mole)

In the above reaction, it can be seen that 1 mole of TiO2 reacts with 2 mole of Cl2 to form 1 mole of TiCl4.

∴ 1.25 mole of TiO2 will react with 2.5 mole of Cl2 to form 1 mole of TiCl4.

Now, 1 mole of Cl2 = 70 g

∴ 2.5 mole of Cl2 = 70 X 2.5 = 175 g

Thus, for complete reaction of 1.25 mole of TiO2, 175 g of Cl2 will be required.
