Question

On the following collective properties, which be used purchased for determining the extent of protein appropriates? Osmotic pressure freezing point depression bulling point election solvent vapor pressure bowering solute vapor pressure calculate the ionic strengths of 0.200 m NaCl, Na_2So_4, and Ca_3(PO_4)_2; what morality of Na_2So_4 is needed to have the same ionic strength as 0.200 m Ca_3(PO_4)_2? Determine E degree and delta G degree for the following overall reaction: Au^3+ _ 3e^- rightarrow Au E = +1.498 V Au rightarrow Au^+ + e^- E = +1.498 V Au^3+ _ 2e^- rightarrow Au^+ E degree_ overall = ? delta G^degree_ overall =?

Explanation / Answer

Of the following colligative properties which is used practical   for determining the extent of   protein aggregation ?

answer :Freezing point depression

Freezing-point depression

It is the procedure in which adding a solute to a dissolvable reductions the point of solidification of the dissolvable. Examples include

salt in water,

alcohol in water, or the mixing of two solids .

=====================================

Calculate the ionic strength of 0.200 m Nacl ,na2so4

What is ionic strength of 0.2 M NaCl solution?

µ = 1/2 ([Na+]z. Na. ^2 + [Cl-]z. Cl^2).

= 1/2 (0.2 (1)^2 + 0.2(-1)^2) = 0.2M

=======================================================================

What is ionic strength of 0.2 M Na2SO4 solution?

[Na+] = 2 x [Na2SO4]

µ = 1/2([Na+]zNa^2 + [SO4-2]zSO4^2) = 1/2(0.4 (1)^2 + 0.2 (-2)^2) = 0.6 M
