Questions and Answers

What are the three types of solutions based on the state of the solute and solvent?

The three types of solutions are gas-gas, liquid-gas, and solid-gas.

Explain the difference between solute and solvent.

Solute is the item dissolved in a solution, while solvent is what the solute is dissolved in.

Define the terms saturated, unsaturated, and super-saturated as related to solutions.

Saturated means no more solute will dissolve, unsaturated means able to dissolve more solute, and super-saturated means it contains more solute than will dissolve under ordinary conditions.

Explain the difference between molarity and molality.

<p>Molarity is moles of solute per liters of solution, while molality is moles of solute per kilograms of solvent.</p> Signup and view all the answers

What is the difference between dilute and concentrated solutions?

<p>Dilute solutions have a relatively little amount of solute, while concentrated solutions have a relatively large amount of solute.</p> Signup and view all the answers

Explain the difference between molarity and molality and how they are calculated.

<p>Molarity is the number of moles of solute per liter of solution, while molality is the number of moles of solute per kilogram of solvent. Molarity is calculated as moles of solute divided by liters of solution, while molality is calculated as moles of solute divided by kilograms of solvent.</p> Signup and view all the answers

What are the differences between saturated, unsaturated, and super-saturated solutions?

<p>A saturated solution contains the maximum amount of solute that can dissolve at a given temperature, an unsaturated solution can dissolve more solute, and a super-saturated solution contains more solute than would normally dissolve under ordinary conditions.</p> Signup and view all the answers

How does the composition of a dilute solution differ from that of a concentrated solution?

<p>A dilute solution contains a relatively little amount of solute compared to the solvent, while a concentrated solution contains a relatively large amount of solute compared to the solvent.</p> Signup and view all the answers

What are the different types of solutions based on the state of the solute and solvent? Provide examples for each type.

<p>The different types of solutions based on the state of the solute and solvent are gas-gas (e.g., air, natural gas), liquid-gas (e.g., carbonated water), liquid-liquid (e.g., alcohol and water), solid-gas (e.g., hydrogen in platinum), and solid-liquid (e.g., sea water).</p> Signup and view all the answers

Define molarity and explain why it is not constant with temperature changes.

<p>Molarity is defined as moles of solute per liters of solution. It is not constant with temperature changes because liquids change density with temperature.</p> Signup and view all the answers

Why is molarity not constant with temperature changes? What property of the solvent affects molarity?

<p>Molarity is not constant with temperature changes because liquids change density with temperature. The property of the solvent that affects molarity is its density.</p> Signup and view all the answers
