![]() the water moolecules collide with the surface of the crystal. when a crystal of an ionic compound is placed in water. you must examine the bonding and polarity of the particles and the intermolecular forces among particles. solvation in water is called hydration to determine whether a a solvent and solute are alike. the solvent particles pull the solute particles apart and surround them solvation the process of surrounding solute particles to form a solution. if the attractive forces between the solvent and solute particles are greater than the attractive forces holding the solute particles together. the solvent particles completely surround the surface of the solid solute. when a solid solute is placed in a solvent. between the pure solvent particles, and between the solute and solvent particles. (m) A solution containing _ mol of solute per kilogram of solvent is a one-molal solution 1 mole fraction the ratio of the number of moles of solute or solvent in solution to the total number of moles of solute and solvent. temperature as it expands or contracts change in volume alters the molarity of a solution, true or false true mass does not change with temperature, true or false true molality the ratio of the number of moles of solute dissolved in 1 kg of solvent. a concentrated solution contains a fairly high ratio of solute particles to solvent particles. tru or false truuuuuuu moles of solute in the stock solution = moles of solute after dilution dilation equation m1v1 = m2v2 before dilution. increase the total number of moles does NOT change during dilation. true When you add solvent, you _ the number of solvent particles among which the solute particles move, thereby decreasing the solution's concentration. True or false? a concentrated solution has a large amount of solute. percent by mass mass of solute / mass of solution x 100 percent by volume volume of solute / volume of solution x 100 molarity the number of moles of solute dissolved per liter of solution. immiscible concentration measure of how much solute is dissolved in a specific amount of solvent or solution. insoluble two liquids that can be mixed together but separate shortly after are said to be. miscible a substance that does not dissolve in a solvent is said to be. ![]() solute the substance that dissolves solvent the dissolving medium true or false? a solution might exist as a gas, solid, or a liquid depending on the state of its solvent true a substance that dissolves in a solvent is said to be _ in that solvent soluble Two liquids that are soluble in each other in any proportion are said to be. amount of colloid particles in suspension solutions homogeneous mixtures that contain two or more substances called the solute and the solvent. the tyndall effect the tyndall effect can be used to determine. the Tyndall effect suspensions also exhibit. dispersed colloid particles scatter light, a phenomenon known as. Dilute colloids appear to be homogeneous solutions bc their dispersed particles are so small. concentrated colloids are often cloudy or opaque dilute colloids sometimes appear as clear as solutions. collisions of particles of the dispersion-medium with the dispersed particles. This erratic movement of colloid particles is the brownian motion. ![]() Brownian motion the dispersed particles of liquid colloids make jerky, random movements. the dispersed particles will clump together, destroying the colloid. if you interfere with the electrostatic lloid particles will settle out the mixture If you stir an electrolyte into a colloid. it gives colliding particles enough kinetic energy to overcome the electrostatic forces and settle out. the dispersed particles collide thus, the particles remain in the colloid. The areas on their surfaces attract the positively or negatively charged areas of the dispersing-medium particles. This results in the formation of electrostatic layers around the particles. ![]() True The dispersed particles in a colloid are prevented from settling out bc.they often have polar or charged atomic groups on their surfaces. True or False? Milk is a colloidal emulsion because liquid particles are dispersed in a liquid medium.
