| Solutions | Amount of Solute |
| --------- | ---------------- |
| X | 10 g |
| Y | 12 g |
| Z | 8 g |

A. [tex]$X \rightarrow Y \rightarrow Z$[/tex]
B. [tex]$Y \rightarrow X \rightarrow Z$[/tex]
C. [tex]$Z \rightarrow X \rightarrow Y$[/tex]
D. [tex]$Y \rightarrow Z \rightarrow X$[/tex]
Answer (2)
Identify the amount of solute dissolved for each solution.
Compare the amounts to determine the order of solubility.
Rank the solutions from greatest to least solubility: Y -> X -> Z.
The final answer is Y r i g h t a rro wX r i g h t a rro wZ .
Explanation
Understanding the Problem We are given a table that shows the amount of solute that fully dissolved in 500 ml of water for three different solutions: X, Y, and Z. We need to rank these solutions in order of greatest to least solubility. Solubility refers to the ability of a solute to dissolve in a solvent. In this case, the greater the amount of solute that dissolves in the water, the higher the solubility of the solution.
Identifying the Solubilities From the table, we can see the following:
Solution X: 10 g of solute dissolved
Solution Y: 12 g of solute dissolved
Solution Z: 8 g of solute dissolved
Ranking the Solutions To rank the solutions from greatest to least solubility, we compare the amounts of solute dissolved. Solution Y has the highest amount of solute dissolved (12 g), followed by Solution X (10 g), and then Solution Z (8 g). Therefore, the order of solubility from greatest to least is Y -> X -> Z.
Final Answer The solutions ranked in order of greatest to least solubility are Y, X, and Z. This corresponds to the option Y r i g h t a rro wX r i g h t a rro wZ .
Examples
Understanding solubility is crucial in many real-world applications. For example, when making coffee, the solubility of coffee grounds in hot water determines the strength of the brew. Similarly, in pharmaceuticals, the solubility of a drug in the body's fluids affects its absorption and effectiveness. In environmental science, the solubility of pollutants in water determines their spread and impact on ecosystems. By understanding the factors that affect solubility, we can optimize processes in various fields, from cooking to medicine to environmental protection.
The solutions ranked in order of greatest to least solubility are Y, X, and Z. This corresponds to the multiple-choice option B: Y → X → Z . Therefore, the correct answer is option B.
