Indicate whether the following statements are TRUE or FALSE. Impurity point defects are found in solid solutions of which there are two types: substitutional and interstitial. TRUE/FALSE Interstitial diffusion involves the interchange of an atom from normal lattice position to adjacent vacant lattice site or vacancy. TRUE/FALSE For an edge dislocation, dislocation line and Burgers vector are parallel. TRUE/FALSE The maximum concentration of solute atoms that may dissolve in the solvent to form solid solution is called solubility limit. TRUE/FALSE...

Which of the following (a-d) is TRUE regarding solid NaCl dissolving in water The attraction of the water to the ions in NaCl is through dipole-dipole IFs. Water is considered the solute and NaCl the solvent. The partially positive oxygen in water is attracted to the chloride ion. d. The process of separating the sodium ions from the chloride ions is endothermic. All of these statements are true. polar For the following solution, describe the deviation with respect...

Which of the following statements is false regarding solubility? A. A saturated solution can be in dynamic equilibrium with undissolved solute. B. The solubility of a solute is independent of the nature of the solvent. C. Solubilities of substances vary with temperature. D. Ionic compounds are not normally very soluble in nonpolar solvents. A saturated solution of MgF_2 contains 1.6 times 10-3 mol of MgF_2 per liter at a certain temperature. What is the K_sp of MgF_2 at this temperature?...

Saturated, Unsaturated & Supersaturated Solutions Solution, in which the concentration of solute is that determined by its solubility (at given temperature) is called SATURATED solution. One cannot add more solute to such a solution. We also say that a saturated solution is in equilibrium with pure solute: If we add solid Nacl to an already saturated solution of NaCl, that solid remains in equilibrium with dissolved Naci. Solution containing less solute than would be in the saturated solution, is UNSATURATED...
