The entities of a solid phase may be arranged in a regular, repeating pattern (crystalline solids) or randomly (amorphous). 'X' shows a gas and 'Y' shows a liquid. Dr. These rods are usually inert, as in they do not react- usually graphite or platinum. ICSE Solutions for Class 10 Chemistry . This produces abnormal grain growth (AGG), which may be desired or detrimental to the produced solid. Definite mass, volume and shape; short inter molecular distances; strong intermolecular forces; constituent particles have fixed position and can only oscillate about their mean positions; incompressible and rigid. For example, asolution of table salt, or sodium chloride (NaCl), in water would be represented as Na+(aq) + Cl−(aq). (c) cations (d) anions. Essential ideas. We then give some examples of the structure of several molten salts, as yielded by the simulations. In particular, we discuss the importance of polarization effects for obtaining accurate results. Œ Such ions can deform to stabilize transition state geometries of the migrating ion through covalent interactions. Explain. 2. (iii) Intermolecular forces are strong. It is usually shown in chemical equations by appending (aq) to the relevant chemical formula. 1. Sodium conducts in the solid and molten states Reason for conductivity of Na mark M2: Sodium has delocalised electrons (in both solid and liquid state) The four main states of matter are solids, liquids, gases, and plasma. Ionic solids act as an insulator in a solid-state but are conductors in a molten and aqueous state. But, in the molten state or when ionic solids are dissolved in water, the ions become free to move about so they conduct electricity. Molten lead bromide, PbBr 2 (l), is an electrolyte. In molten sodium chloride, the only available ions are $\ce{Na^+}$ and $\ce{Cl^-}$. Example: NaCl, MgO, ZnS, CaF 2 etc. 1.
