5 True/False questions
Brownian motion → The jerky, random, rapid movements of colloid particles that results from collisions of particles of the dispersion medium with the dispersed medium.
colloid → Hetergeneous mixtures containing particles larger than solution particles but smaller than suspension particles that are categorized according to the phases of their dispersed particles and dispersing mediums.
miscible → Describes two liquids that are soluble in each other.
concentration → The ratio of the number of moles of solute in solution to the total number of moles of solute and solvent.
mole fraction → The process of surrounding solute particles with solvent particles to form a solutions; occurs only where and when the solute and solvent particles come in contact with each other.
