What is a solution?

Back

A solution is a homogeneous mixture composed of two or more substances, where one substance (the solute) is dissolved in another (the solvent).

Front

Define solubility.

Back

Solubility is the ability of a substance (solute) to dissolve in a solvent at a given temperature and pressure.

Front

What factors affect solubility?

Back

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

Front

What is molarity?

Back

Molarity (M) is a measure of concentration, defined as the number of moles of solute per liter of solution.

Front

How do you calculate moles from volume and molarity?

Back

Moles = Molarity (M) × Volume (L).

Front

What is the molarity of a solution containing 2 moles of solute in 4 liters of solution?

Back

0.5 M (2 moles / 4 L = 0.5 M).

Front

What is the formula to find the mass of solute in grams?

Back

Mass (g) = Moles × Molar Mass (g/mol).

Front

How do you convert grams of solute to moles?

Back

Moles = Mass (g) / Molar Mass (g/mol).

Front

What is the solubility of NaCl in water at room temperature?

Back

Approximately 357 g of NaCl can dissolve in 1 liter of water at room temperature.

Front

What is the significance of temperature on solubility?

Back

Generally, solubility of solids increases with temperature, while the solubility of gases decreases.
