Concept explainers
(a)
Interpretation:
The equations to represent the positive and negative ion formation for the given pair of elements are to be stated. The formula for the ionic compound that results if the formed ions combine together is to be stated.
Concept introduction:
The species that are formed by losing or gaining the electrons are known as ions. The cations are formed by losing one or more than one electron from the outer most shell of an atom. Anions are formed by gaining one or more than one electron to the outer most shell of an atom.
(b)
Interpretation:
The equations to represent the positive and negative ion formation for the given pair of elements are to be stated. The formula for the ionic compound that results if the formed ions combine together is to be stated.

- The molar absorptivity of a protein in water at 280 nm can be estimated within ~5-10% from its content of the amino acids tyrosine and tryptophan and from the number of disulfide linkages (R-S-S-R) between cysteine residues: Ε280 nm (M-1 cm-1) ≈ 5500 nTrp + 1490 nTyr + 125 nS-S where nTrp is the number of tryptophans, nTyr is the number of tyrosines, and nS-S is the number of disulfide linkages. The protein human serum transferrin has 678 amino acids including 8 tryptophans, 26 tyrosines, and 19 disulfide linkages. The molecular mass of the most dominant for is 79550. Predict the molar absorptivity of transferrin. Predict the absorbance of a solution that’s 1.000 g/L transferrin in a 1.000-cm-pathlength cuvet.
