b) Ideal solutions

c) Conjugate solutions

d) Metastable equilibrium

e) Condensed systems

f) Congruent melting point

g) Ionic mobility

h) Conductivity water

i) Standard electrode potential

j) Concentration cells

Answer 1

a) Molarity is defined as the moles of a solute per liters of a solution.

b) An ideal solution is a solution in which the gas phase exhibits thermodynamic properties analogous to those of a mixture of ideal gases.

c) Conjugate Solutions are solutions formed between two liquids that are partially miscible with one another; such solutions are in equilibrium at a particular temperature.

d) Metastable equilibrium is a condition in which a system returns to equilibrium after small displacements.

e) Condensed System is chemical system in which the vapor pressure is negligible or in which the pressure maintained on the system is greater than the vapor pressure of any portion.

f) Congruent melting is melting wherein a phase melts to a liquid with the same composition as the solid.

g) Ionic mobility is described as the speed achieved by an ion moving through a gas under a unit electric field.

h) Conductivity water is a measure of the ability of water to pass an electrical current.

i) Standard electrode potential is defined as the measure of the individual potential of a reversible electrode at standard state with ions at an effective concentration of 1mol dm⁻³ at the pressure of 1 atm.

j) A concentration cell is an electrolytic cell that is comprised of two half-cells with the same electrodes, but differing in concentrations.
