To solve the problem, we need to identify the
solute and the
solvent in each given solution. The key hint provided is that the
solvent is always present in a greater amount than the solute.
Definitions:
-
Solute: The substance that is dissolved in the solvent.
-
Solvent: The substance that dissolves the solute and is present in a greater amount.
Step-by-Step Analysis:
1.
Cigarette Smoke (Air)
-
Solution: Cigarette smoke spread through air.
-
Solute: Cigarette smoke particles (smaller amount).
-
Solvent: Air (greater amount).
-
Answer: Solute: Cigarette Smoke; Solvent: Air.
2.
Copper (Gold)
-
Solution: Gold ring containing copper.
-
Solute: Copper (smaller amount, typically an alloy component).
-
Solvent: Gold (greater amount, the primary metal).
-
Answer: Solute: Copper; Solvent: Gold.
3.
Caffeine (Water)
-
Solution: Cup of coffee.
-
Solute: Caffeine (smaller amount, dissolved in water).
-
Solvent: Water (greater amount, the liquid medium).
-
Answer: Solute: Caffeine; Solvent: Water.
4.
Silver (Copper)
-
Solution: Sterling silver.
-
Solute: Copper (smaller amount, typically an alloy component).
-
Solvent: Silver (greater amount, the primary metal).
-
Answer: Solute: Copper; Solvent: Silver.
5.
Water (Oxygen)
-
Solution: Water in a fish tank.
-
Solute: Oxygen (smaller amount, dissolved in water).
-
Solvent: Water (greater amount, the liquid medium).
-
Answer: Solute: Oxygen; Solvent: Water.
6.
Carbon Dioxide (Sugar Water)
-
Solution: Sealed can of pop.
-
Solute: Carbon dioxide (smaller amount, dissolved gas).
-
Solvent: Sugar water (greater amount, the liquid medium).
-
Answer: Solute: Carbon Dioxide; Solvent: Sugar Water.
7.
Oxygen (Nitrogen)
-
Solution: Air.
-
Solute: Oxygen (smaller amount, one of the components of air).
-
Solvent: Nitrogen (greater amount, the most abundant component of air).
-
Answer: Solute: Oxygen; Solvent: Nitrogen.
Final Answer:
\[
\boxed{
\begin{array}{ccc}
\text{Solution} & \text{Solute} & \text{Solvent} \\
1. \text{Cigarette Smoke (Air)} & \text{Cigarette Smoke} & \text{Air} \\
2. \text{Copper (Gold)} & \text{Copper} & \text{Gold} \\
3. \text{Caffeine (Water)} & \text{Caffeine} & \text{Water} \\
4. \text{Silver (Copper)} & \text{Copper} & \text{Silver} \\
5. \text{Water (Oxygen)} & \text{Oxygen} & \text{Water} \\
6. \text{Carbon Dioxide (Sugar Water)} & \text{Carbon Dioxide} & \text{Sugar Water} \\
7. \text{Oxygen (Nitrogen)} & \text{Oxygen} & \text{Nitrogen} \\
\end{array}
}
