Question | Answer |
---|---|
What is the dissolved substance? | The solute |
What are non electrolytes? | solutes that dissolve in water but don't form electric currents |
Colloid | A mixture in which one substance of microscopically dispersed insoluble particles is suspended throughout another substance |
what can solutions consist of? | solutes and solvents consisting of solids, gases and liquids |
solutes and solvents consisting of solids, gases and liquids | solubility depends on the temperature |
what is a molar concentration of a solution | The molar concentration of a solution represents the ratio of moles of solute to liters of solution |
What are mixtures classified as? | solutions, suspensions, colloids, depends on the size of the mixture's particle |
What are electrolytes | Electrolytes are the most ionic solutes and some molecular solutes form aqueous solutions that conduct an electric current |
Molarity | Concentration unit defined to be the number of moles of solute divided by the number of liters of solution |
Hydration | Chemical reaction in which a substance combines with water |
What are the two types of mixtures | homogeneous or heterogeneous |
The solubility of gases in liquids increases with | increase in pressure |
The solubility of gases in liquids decreases with | increase in temperature |
What are the two useful expressions of concentration | Molarity and molaity |
Suspension | a mixture in which particles of a material are more or less evenly dispersed throughout a liquid or gas |
