Question
The non-stoichiometric compound, titanium monoxide, has a continuous range of composition from Ti0.75O to TiO0.69. Which of the following is/ are the correct regarding the possible composition of the compound?
[Ti = 48]
Options
A.The maximum percentage by mass of oxygen in the compound is 30.8.
B.The minimum percentage by mass of titanium in the compound is 69.2.
C.The minimum percentage by mass of oxygen in the compound is 18.7.
D.The minimum percentage by mass of titanium in the compound is 81.3.
Solution
For Ti0.75O = 0.75 × 48 + 16 = 52
∴ Percentage of Ti =$\frac{36}{52}$× 100 = 69.23% and percentage of O = 30.8%
For TiO0.69 = 48 + 16 × 0.69 = 59.04
∴ Percentage of Ti =$\frac{48}{59.04}$ × 100 = 81.3% and percentage of O = 18.7%
