NaCl when placed in a uniform electric field 20VM^-1 , both Na^+ and Cl^- ions experience a force (average distance between Na^+ and Cl^- is 1.3A). Br In what way the NaCl will orient in the electric field.

NaCl when placed in a uniform electric field 20Vm^-1 , both Na^+ and Cl^- ions experience a force (average distance between Na^+ and Cl^- is 1.3A). Br Calculate the maximum torque experience by the NaCl molecule in the electric field.

Assertion : On the addition of conc. HNO_(3) to the aqueous solution of common salt, NaCl crystallises out Reason : After the reaction between conc. HNO_(3) and hydrated ions, the water molecules are removed and the ions are thus unsolvated. (I) Both assertion and reason are true and reason is the correct explanation of assertion (II) Both assertion and reason are true and reason is not the correct explanation of assertion (III) Assertion is true and reason is false (IV) Assertion is true and reason is false
