Question 85

When titanium reacts with chlorine gas, a titanium chloride is formed.

Two possible equations for this reaction are:

A

2Ti+3Cl2→2TiCl3 2\text{Ti} + 3\text{Cl}_2 \rightarrow 2\text{TiCl}_3 2Ti+3Cl2​→2TiCl3​

B

Ti+2Cl2→TiCl4 \text{Ti} + 2\text{Cl}_2 \rightarrow \text{TiCl}_4 Ti+2Cl2​→TiCl4​

It was found that 9.58 g of titanium reacted with excess chlorine to produce 37.98 g of titanium chloride.

Carry out a calculation to decide which equation, A or B, represents the reaction taking place. (Relative atomic masses: Ti=47.9\text{Ti} = 47.9Ti=47.9, Cl=35.5\text{Cl} = 35.5Cl=35.5)
