PC #09 Solubility, Solutions, NIE, Molarity

Front

What is a solute?

Back

A solute is a substance that is dissolved in a solvent to form a solution. In a mixture of powder and water, the powder is the solute.

Front

What is a solvent?

Back

A solvent is a substance that dissolves a solute, resulting in a solution. In a saltwater solution, water is the solvent.

Front

What is a solution?

Back

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

Front

What is molarity?

Back

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

Front

What is the dissociation equation for NaCl?

Back

NaCl(s) → Na⁺(aq) + Cl⁻(aq) - This shows how solid sodium chloride dissociates into its ions in water.

Front

What are strong electrolytes?

Back

Strong electrolytes are substances that completely dissociate into ions in solution, making them good conductors of electricity.

Front

What is the result of mixing potassium bromide (KBr) and ammonium sulfide (NH₄S)?

Back

No precipitate is formed when potassium bromide and ammonium sulfide are mixed.

Front

Is ammonium nitrate (NH₄NO₃) soluble in water?

Back

Yes, ammonium nitrate is soluble in water.

Front

What is the difference between soluble and insoluble substances?

Back

Soluble substances can dissolve in a solvent, while insoluble substances do not dissolve significantly.

Front

What is a precipitate?

Back

A precipitate is a solid that forms and settles out of a liquid mixture during a chemical reaction.
