A student is carrying out a biological preparation that requires 1 M NaCl to maintain an ionic strength of 1.0. The student choo
nignag [31]

Explanation:

The ionic strength of a solution, I, is defined as

I=1/2 Σ m_i z_i^2

Where m_i is the concentration of the ion, and z_i is the charge of the ion.

For 1 M NaCl solution, Ionic strength I = ½ (1*12 + 1*12) = 1.00;

For, 1 M (NH4)2SO4, concentration of [NH4] = 2 M and [SO4] = 1 M;

I = ½ (2*12 + 1*22) = 3.00;

so ionic strength of 1 M (NH4)2SO4 is different, therefore it is a serious error.

Why is there such a large jump and ionization energy between the second and third ionization energy‘s for magnesium?
Romashka [77]
The second ionization energy of Mg is larger than the first because it always takes more energy to remove an electron from a positively charged ion than from a neutral atom. The third ionization energy of magnesium is enormous, however, because the Mg2+ ion has a filled-shell electron configuration.
