Chapter 3 - Solutions
Fichas del conjunto (26)
- 1homogeneous mixturea mixture where the components are uniformly mixed and has only one phase (visible part)
- 2heterogeneous mixturecontains two or more phases
- 3solutiona homogeneous mixture of two or more substances
- 4solutea substance that is in a lesser quantity in a solution
- 5solventthe substance that is in the greater quantity in a solution
- 6concentrationthe ratio of the quantity of solute to the quantity of solution or solvent; usually the quantity of solute per unit volume of solution
- 7concentrated solutiona solution with a relatively large quantity of solute dissolved per unit volume of solution
- 8dilute solutiona solution with a relatively small quantity of solute dissolved per unit volume of solution
- 9misciblewhen two liquids are mixed together and they are evenly spread
- 10immisciblewhen two liquids do not mix together
- 11alloya solution of two or more metals
- 12amalgaman alloy (solution) of mercury with other metals
- 13aqueous solutiona solution in which water is the solvent
- 14solubilitythe maximum mass of solute that can be dissolved per 100g of water at a given temperature
- 15saturated solutiona solution that contains the maximum quantity of solute at a given temperature and pressure
- 16unsaturated solutiona solution in which more solute can dissolve at a given temperature and pressure
- 17supersaturated solutiona solution that contains more than the maximum quantity of solute than it should at a given temperature and pressure
- 18equilibriumthe balance that exists when two opposing processes occur at the same rate
- 19solubility curvea graph of the solubility of a substance over a range of temperatures
- 20acida compound which releases hydrogen ions when dissolved in water
- 21basea substance which accepts protons
- 22molar concentrationthe number of moles of solute in 1L of solution
molar concentration (mol/L) =
moles of solute (n) / volume of solution (L) - 23formulasC= n/v
n= C•v
v= n/C - 24dissociationoccurs when an ionic compound breaks into ions as it dissolves in water
- 25electrolyte-a solute that conducts an electronic current in an aqueous solution
-solutions of ionic compounds conduct electric current
(acids are also electrolytes, they form ions when dissolved in water) - 26non-electrolytes-molecular compounds do not dissociate in water
-they do not conduct electric current in solution
