Please fill in the solute and solvent for each pair of substances.

Answer 1

A solution consists of a solute and a solvent mixed together to form a homogeneous mixture. Five pair examples that form solutions include alcohol and water, salt and water, coffee powder and water, sugar and water, and carbon dioxide and water, with water always being the solvent. Additional information includes examples of types of solutions, definition of saturated and concentrated solutions, and classification of different substances.

Step-by-step explanation:

To identify the pair of substances that produces a solution, we need to know that a solution is a homogeneous mixture composed of a solute (that is dissolved) and a solvent (that does the dissolving). Here are five pairs that form a solution, along with the identification of the solute and the solvent:

1. Alcohol and Water - Alcohol is the solute, and water is the solvent.
2. Salt and Water - Salt is the solute, and water is the solvent.
3. Coffee Powder and Water - Coffee powder is the solute, and water is the solvent.
4. Sugar and Water - Sugar is the solute, and water is the solvent.
5. Carbon Dioxide and Water - Carbon Dioxide is the solute, and water is the solvent.

Additional Exercises

• In the brand of ethyl alcohol Everclear, which is 95% ethyl alcohol, ethyl alcohol is the solute and water is the solvent.
• Examples of types of solutions from personal experience could include:

1. A sodated beverage like a cola, where the gas (carbon dioxide) is the solute and the liquid (water) is the solvent.
2. Saltwater, where the solid (salt) is the solute and the liquid (water) is the solvent.
3. Alcoholic beverages such as vodka, with ethanol (liquid) as the solute and water as the solvent.
4. Alloys like bronze, where tin (solid) is the solute and copper (solid) is the solvent.

Definitions:

• A saturated solution is one in which no more solute can be dissolved at a given temperature.
• A concentrated solution has a large amount of solute in a given volume of solvent.

Identification of substances:

• White wine is a homogeneous mixture (solution).
• Mercury is an element.
• Ranch-style salad dressing is a heterogeneous mixture.
• Table sugar (sucrose) is a compound.
