Which of the properties of interstitial hydrides is correct?

Options

A. They generally for non-stoichiometric species
B. The hydrogen dissolved in titanium improves its mechanical properties
C. They give rise to metals fit for fabrication
D. On thermal decomposition, they afford a source of pure hydrogen

Answer

A

Explanation

The interstitial hydrides are generally non-stoichiometric and their compositions vary with temperature and pressure. For example `TiH_(1.73), CeH_(2.7), LaH_(2.8).` etc .
