Terms in this set (32)T or F The ocean is a "solution" because it is a mixture of salts and water. True T or F The process called "dissociation" separates ionic crystals into ions. False - ionization T or F Hydrocarbons are nonpolar because they have an "unequal" distribution of electrons. False - equal T or F A general statement that describes which substances dissolve which is 'like dissolves "unlike"' False - like T or F A substance that produces ions in a water is a "nonelectrolyte." False - electrolyte T or F Generally, the concentration of a liquid dissolved in a liquid can be expressed asa percentage by "mass" False - volume T or F A gas dissolves in a liquid most rapidly when under "low" pressure False - high T or F Nail polish can be dissolved by the "nonpolar" Solent acetone True T or F Adding a solute to a solvent "raises" the freezing point of the solvent. False - lowers T or F Adding a solute to a solvent "raises" the boiling point True T or F A supersaturated solution is "more" stable than a saturated solution. False - less T or F A solid dissolves faster when it is ground because grinding "decreases" surface area False - increases A solution that contains all of the solute it can normally hold at a given temperature is...

The moving molecules of the solvent surround the molecules of the solute. Increasing the surface area of a solid... Increases the speed of dissolving Which of the following types of solutes dissolves well in water? Polar molecules In a solution, the substance that is being dissolved is the... Solute The process by which the particles in a crystal are separated and drawn into solution by water is called... Dissociation An alloy is an example...solution. Solid Adding more solute to a solvent... Raises its boiling point Water is sometimes referred to as the universal solvent because... It is a small molecule and can fit easily among the molecules of many solutes. Soap has a(n)...end that will dissolve in water and a long hydrocarbon proton that will dissolve in oily dirt. Ionic The maximum amount of a solute that can be dissolved in a given amount of solvent is its... Solubility Which of he following combinations would increase the solubility of a gas in a liquid? Increase the pressure and decrease the temperature The solubility of a gas in a liquid occur faster if the liquid is... Cooled The concentration of a solution that contains a large amount of solute in the solvent could be described as... Concentrated Which of the following substances would dissolve iodine? Ethanol How many grams of water are needed to make 100 g of a 20% saltwater solution? 80 grams If you had a saturated solution of NaCl at 80 degrees Celsius, what would happen if you let it cool to 40 degrees Celsius? Part of the NaCl would come out of the solution. Why should you be careful to take the right amounts of different vitamins? Water-soluble vitamins such as Vitamin C are flushed regularly out of the body and need to be replenished often. Fat-soluble vitamins such as Vitamin A, on the other hand, remain and accumulate in our fatty tissues. Fat-soluble vitamins should be taken in recommended doses only. Why does breaking up a solid solute into smaller pieces help it dissolve more quickly? When the surface area of the solute is increased, more molecules of solvent can come into contact with more molecules of solute. This speeds up the dissolving process.

The molecules of both these substances start interacting, and as a result, the solute molecules move away from each other and are surrounded by the solvent molecules.
What are the 3 steps in the dissolving process?Energetically the dissolution of a solid into a solvent to form a solution can be envisioned to occur in three steps. Step 1: Separation of pure solid into separated particles. Step 2: Separation of pure solvent into separated particles. Step 3: Combining the particles into a solution.
What is the process of dissolving?Dissolving happens when the attraction between the particles of the solvent and solute are strong enough to overcome the attraction of the particles of the solute for one another. Evaporation happens when water molecules move fast enough to break away from a solution and move into the air.
What is the dissolving process of water?The three stages are: the stage of surface water development (the first stage), the stage of comprehensive development of surface and ground water (the second stage) and the stage of economical development of water resources (the third stage).
