Question
### Identifying Acidic, Basic, or Neutral Solutions at Various Temperatures **Question:** Identify the following condition as representing an acidic, basic, or neutral solution at 25°C, 37°C, and 60°C. For each condition below, you want to consider that value at each temperature. **Conditions:** a) pH = 3.54 b) pH = 8.25 c) pOH = 7.00 d) pOH = 10.43 e) pOH = 2.25 To determine if a solution is acidic, basic, or neutral, we can use the pH and pOH values at different temperatures. The following guidelines can help: - **Neutral solution:** pH = 7 (at 25°C, pH = 7.00). This changes with temperature. - **Acidic solution:** pH < 7 (lower in acidic nature). - **Basic solution:** pH > 7 (higher in basic nature). To further understand: - pH is the measure of hydrogen ion concentration in a solution. - pOH is the measure of hydroxide ion concentration and is given by pOH = 14 - pH at 25°C (Neutral pH = 7). Considering changes in temperature: - At higher temperatures, the neutral point (pH) decreases because the ionization of water increases, leading to more \( H^+ \) and \( OH^- \) ions. **Analyzing Each Condition:** a) **pH = 3.54** - At 25°C: Acidic (pH < 7) - At 37°C: Still acidic, but neutrality point might be slightly lower than 7, thus pH 3.54 remains acidic. - At 60°C: Neutrality might be lower than 7, but pH 3.54 is still acidic. b) **pH = 8.25** - At 25°C: Basic (pH > 7) - At 37°C: Still basic, given neutrality shifts downward. - At 60°C: Still basic as it's above the shifting neutrality value. c) **pOH = 7.00** - At 25°C: Neutral (pH = 14 - 7 = 7) - At 37°C: Might still indicate
