What are the characteristics of ideal (or nearly ideal) solutions? o a. they follow raoult's law, which means partial pressure of components a and b in a solution will be pia] = piao! times x[a] and pib-p[bol times x[b] where pia0] and p[bo] are respective vapour pressure in pure form and x[a] and x[b] are respective mole fractions of components a and b ia) and pib) piboj times x1b] where piao] and pibo] o b. the enthalpy of mixing of two components should be zero. this signifies that no heat is released or absorbed during mixing of two pure components to form ideal solution. o c. the volume of mixing of two components should be zero. this means that total volume of solution is equal to the sum of the volume of solute and solution. adding further, it also signifies that there is no occurrence of contraction or expansion of volume while mixing of two components. o d. the solute-solute interaction and solvent-solvent interaction is nearly equal to solute- solvent interaction. o a, b and c o a, b and d o all of the above
