Passage / Comprehension

A large number of silicate minerals exist in nature. Some examples include feldspar, zeolites, mica, and asbestos. The basic structural unit of silicates is the $(S i O_{4})^{4 -}$ anion, in which a silicon atom is bonded to four oxygen atoms in a tetrahedral fashion. In silicates, either the discrete $S i O_{4}^{4 -}$ unit is present, or a number of such units are joined together via corners by sharing 1, 2, 3, or 4 oxygen atoms per silicate unit. When silicate units are linked together, they form chain, ring, sheet, or three-dimensional structures. The negative charge on the silicate structure is neutralized by positively charged metal ions. If all four corners are shared with other tetrahedral units, a three-dimensional network is formed.

(a) Tetrahedral structure of the $S i O_{4}^{4 -}$ anion

(b) Representation of the $S i O_{4}^{4 -}$ unit

$BaTi^{2} [Si_{3} O_{9}]$ is a class of

Options:

Answer:

B

Solution:

Since $Ba^{2 +}$ and $Ti^{4 +}$ combined with $Si_{3} O_{9}^{6 -}$ which contain $(SiO_{3}^{2 -})_{3}$ it is cyclic silicates
