Key Insights

KI is the most soluble major chemical at \(60°\mathrm{C}\) among those listed. \(\mathrm{NH_4Cl}\) sharply increases in solubility with temperature and could reach the same solubility as \(\mathrm{KClO_3}\) at a temperature above \(100°\mathrm{C}\), assuming curve trends continue. Different chemical solubility curves show unique shapes, indicating variable responses to heating: most increase, but some (like \(\mathrm{SO_2}\)) decrease with temperature.

Step-by-Step Solution

Question 1: Most Soluble Chemical at \(60°\mathrm{C}\)

Complete Statement:

At \(60°\mathrm{C}\), the most soluble of the chemicals is most likely [BLANK].

Breaking Down the Statement

• Statement Breakdown 1:
  • Key Phrase: At \(60°\mathrm{C}\)
    Meaning: We are asked to focus specifically on the temperature of \(60°\mathrm{C}\).
    Relation to Chart: Examine the solubility values for each chemical at \(60°\mathrm{C}\) on the solubility curves.
    Important Implications: No need to analyze trends, just compare the actual values at this particular temperature.
• Statement Breakdown 2:
  • Key Phrase: most soluble
    Meaning: The chemical that dissolves in the largest amount at the given temperature.
    Relation to Chart: Look for the highest solubility value (highest point on the y-axis) at \(60°\mathrm{C}\) among the choices.
    Important Implications: We are looking for the chemical whose curve is highest at \(60°\mathrm{C}\).
• What is needed: Which of the given chemicals has the highest solubility (grams per 100g water) at \(60°\mathrm{C}\).

Solution:

• Condensed Solution Implementation:
  Check the solubility values at \(60°\mathrm{C}\) for each answer-choice chemical by finding where the vertical \(60°\mathrm{C}\) line meets each curve.
• Necessary Data points:
  At \(60°\mathrm{C}\), estimated solubility values are:
  • KI ≈ \(140 \mathrm{g/100g H_2O}\)
  • \(\mathrm{NaNO_3}\) ≈ \(120 \mathrm{g/100g H_2O}\)
  • \(\mathrm{KNO_3}\) ≈ \(110 \mathrm{g/100g H_2O}\)
  • KCl ≈ \(45 \mathrm{g/100g H_2O}\)
  • \(\mathrm{SO_2}\) is not shown at this temperature and is much lower when present.
  Calculations Estimations: Visually compare values; no math needed. KI is the highest among the choices at \(60°\mathrm{C}\).
  Comparison to Answer Choices: KI has the highest solubility at \(60°\mathrm{C}\) among the listed chemicals.

FINAL ANSWER Blank 1: KI

Question 2: Intersection of \(\mathrm{NH_4Cl}\) Solubility Above \(100°\mathrm{C}\)

Complete Statement:

There is most likely a temperature above \(100°\mathrm{C}\) at which \(\mathrm{NH_4Cl}\) is exactly as soluble as [BLANK].

Breaking Down the Statement

• Statement Breakdown 1:
  • Key Phrase: temperature above \(100°\mathrm{C}\)
    Meaning: We're interested in what happens outside the measured chart, extending to higher temperatures.
    Relation to Chart: Consider the direction and slope of solubility curves as they head beyond \(100°\mathrm{C}\).
• Statement Breakdown 2:
  • Key Phrase: \(\mathrm{NH_4Cl}\) is exactly as soluble as
    Meaning: Find another chemical whose solubility matches \(\mathrm{NH_4Cl}\)'s at some point, if both curves were extended beyond \(100°\mathrm{C}\).
    Relation to Chart: Look for curves that might meet or cross \(\mathrm{NH_4Cl}\)'s if extended rightward.
• What is needed: Which chemical's solubility could equal \(\mathrm{NH_4Cl}\)'s at a temperature beyond \(100°\mathrm{C}\) if their trends continue.

Solution:

• Condensed Solution Implementation:
  Observe curve behaviors near \(100°\mathrm{C}\) and estimate which chemical's solubility will intersect \(\mathrm{NH_4Cl}\) as temperature increases above the charted range.
• Necessary Data points:
  At \(100°\mathrm{C}\):
  • \(\mathrm{NH_4Cl}\) ≈ \(75 \mathrm{g/100g H_2O}\) (steep rising curve)
  • \(\mathrm{KClO_3}\) ≈ \(55 \mathrm{g/100g H_2O}\) (also rising, increasingly steep)
  Other answer-choice curves are either well below or nearly flat.
  Calculations Estimations: \(\mathrm{KClO_3}\)'s curve, though below \(\mathrm{NH_4Cl}\) at \(100°\mathrm{C}\), increases more sharply and will likely overtake/intersect \(\mathrm{NH_4Cl}\) above \(100°\mathrm{C}\).
  Comparison to Answer Choices: \(\mathrm{KClO_3}\) is the only answer-choice whose extension plausibly intersects \(\mathrm{NH_4Cl}\)'s curve over \(100°\mathrm{C}\).

FINAL ANSWER Blank 2: \(\mathrm{KClO_3}\)

Summary

Question 1 is answered by comparing actual solubility values at \(60°\mathrm{C}\), where KI stands out as the highest among the provided choices. Question 2 involves projecting existing curve trends, recognizing that only \(\mathrm{KClO_3}\)'s steeply increasing solubility makes it plausible to intersect \(\mathrm{NH_4Cl}\) above \(100°\mathrm{C}\).

Question Independence Analysis

The two questions are independent: one is a single-point comparison, and the other is a forward-looking trend analysis. You do not need the answer to one to work out the other.
