In water NaCl splits into `Na^(+) and Cl^(2+)` ions.

The unit cell of NaCl crystal has 4Na^(+)and4Cl^(-) ions. The edge length of the unit cell is 5.64Å. What is the density of NaCl crystal?

Discuss the biological importance of Na^(+) and K^(+) ions.

Dipole moment of NaCl is 8.5 D. interatomic distance between Na^(+) and Cl^(-) is 2.36 Å. Calculate the percentage of ionic character of NaCl molecule.

X-ray diffraction studies show that edge length of a unit cell of NaCl is 0.56 nm. Density of NaCl was found to be 2.16g//"cc". What type of defect is found in the solid? Calculate the percentage of Na^(+) and Cl^(-) ions that are missing.

At ordinary temperature and pressure, solid NH_(4)Cl dissolves in water to form NH_(4)^(+)(aq) and Cl^(-)(aq) ions. The process is endothermic. Indicate the signs (+ or -) of DeltaS_(sys),DeltaS_("surr"),DeltaH and DeltaG .

A unit call of NaCl has four formula units. In NaCl crystal, radius ratio (r_(+)//r_(-)) is 0.69 and edge-length of the unit cell is twice the sum of the radii of Na^(+)andCl^(-) ions. If the radius of Na^(+) is 116 pm then find the density of NaCl crystal. Formula mass of NaCl = 58.5g*mol^(-1) .

In NaCl, Na^(+) ion has ___________ and Cl^(-) ion has __________ electron configurations

PC l_(5) is highly reactive and in solid state it splits into ions. The shape of these ions are-

Absorption of major part of Na^(+) and K^(+) ions occurs in

NaCl crystal possesses a crystal structure having face-centred cubic unit cell. If the radii of Na^(+)andCl^(-) ions are 95 and 181 pm, respectively, then the edge length of its unit cell is-
