HChem Chap 12 Flashcardizz - Solutions

Front

What is solubility?

Back

Solubility is the maximum amount of solute that can dissolve in a given amount of solvent at a specific temperature and pressure.

Front

Which factors affect solubility?

Back

Factors affecting solubility include temperature, pressure, and the nature of the solute and solvent.

Front

What is a saturated solution?

Back

A saturated solution is one in which no more solute can dissolve at a given temperature.

Front

Define molarity (M).

Back

Molarity is the number of moles of solute per liter of solution.

Front

How do you calculate the number of grams of solute in a solution?

Back

To calculate grams of solute, use the formula: grams = molarity (M) x volume (L) x molar mass (g/mol).

Front

What is molality (m)?

Back

Molality is the number of moles of solute per kilogram of solvent.

Front

How do you calculate molality?

Back

Molality (m) = moles of solute / mass of solvent (kg).

Front

What are electrolytes?

Back

Electrolytes are substances that dissociate into ions in solution and can conduct electricity.

Front

What is a weak electrolyte?

Back

A weak electrolyte is a substance that partially dissociates into ions in solution.

Front

What are London Dispersion forces?

Back

London Dispersion forces are weak intermolecular forces arising from temporary dipoles in molecules.
