(ii) What is meant by piezo electricity?

Text Solution

Verified by Experts

(i) 1. `Na_(2)[Ni(EDTA)]=` Sodium Ethylenediamineteraacetatonickelate (II) (or) Sodium 2,2.,2..,2...-(ethane-1,2-diyldinitrilo) tetraacetatonickelate(II)
2. `[Co(en)_(3)]_(2)(SO_(4))_(3)=` tris(ethylenediamine)cobalt(III) sulphate
(ii) Piezo electricity is the appearance of an electrical potential across the sides of a crystal. When you subject it to mechanical stress. The word piezo electricity means electricity resulting from pressure and latent heat. Even the inverse is possible which is known as inverse piezo electric effect.
