In a solution, the dissolving medium is the _____________. 15.2 Solvents and Solutes An _____________ solution is __________ that contains dissolved substances. In a solution, the dissolving medium is the _____________. In a solution, the dissolved particles are the _____________.

Solvents and solutes may be ___________, __________, __________ 15.2 Solvents and Solutes A solvent ____________ the solute. The solute becomes ____________ in the solvent. Solvents and solutes may be ___________, __________, __________ Solute particles can be ____________, ______________, ____________

15.2 Solvents and Solutes If you filter a solution through filter paper, both the ___________ and the ______________ pass through the filter. A solution cannot be separated by filtration. The small size of the solute particles allows them to pass through filter paper.

15.2 The Solution Process As individual solute ions break away from the crystal, the negatively and positively charged __________ become surrounded by ___________ molecules, and the ionic crystal dissolves.

15.2 The Solution Process The process by which the positive and negative ions of an ionic solid become surrounded by solvent molecules is called ________________.

___________ solvents such as gasoline dissolve __________ compounds. 15.2 The Solution Process __________ solvents such as water dissolve ________ compounds and ____________ compounds. ___________ solvents such as gasoline dissolve __________ compounds. Oil and water do not mix.

Electrolytes and Nonelectrolytes 15.2 Electrolytes and Nonelectrolytes An _________________ is a compound that conducts an electric current when it is in an aqueous solution or in the molten state. All _____________ compounds are _________________ because they dissociate into ions.

Electrolytes and Nonelectrolytes 15.2 Electrolytes and Nonelectrolytes The bright glow shows that sodium chloride is a ____________ ____________________ because nearly all the dissolved sodium chloride exists as separate Na+ and Cl– ions. A solution conducts electricity if it contains ions. a) Sodium chloride, a strong electrolyte, is nearly 100% dissociated into ions in water. b) Mercury(II) chloride, a weak electrolyte, is only partially dissociated in water. c) Glucose, a nonelectrolyte, does not dissociate in water.

Electrolytes and Nonelectrolytes 15.2 Electrolytes and Nonelectrolytes A ____________ __________________ conducts electricity poorly because only a fraction of the solute in the solution exists as ions. A solution conducts electricity if it contains ions. a) Sodium chloride, a strong electrolyte, is nearly 100% dissociated into ions in water. b) Mercury(II) chloride, a weak electrolyte, is only partially dissociated in water. c) Glucose, a nonelectrolyte, does not dissociate in water.

Electrolytes and Nonelectrolytes 15.2 Electrolytes and Nonelectrolytes A compound that does not conduct an electric current in either aqueous solution or the molten state is called a nonelectrolyte. A solution conducts electricity if it contains ions. a) Sodium chloride, a strong electrolyte, is nearly 100% dissociated into ions in water. b) Mercury(II) chloride, a weak electrolyte, is only partially dissociated in water. c) Glucose, a nonelectrolyte, does not dissociate in water.
