Question

i have the option for using the three solutions
table: solution (distilled water, sugar water, lemon juice); change in mass (e.g., +0.5 g, -3.6 g, +0.3 g)
use the data above to create a bar graph showing your results. make sure you create a bar graph with the proper scale. keep in mind that some of your values might be negative, so you will need to fit that into your graph. be sure to label the axis and provide an appropriate title and key.

analysis questions:

1. which solution is an isotonic solution? how do you know? (use data from table)
2. which solution is a hypotonic solution? how do you know? (use data from table)

Explanation:

To solve the problem of identifying isotonic and hypotonic solutions, we analyze the change in mass data (assuming the initial mass of the potato is constant, let's say \( m_0 \)):

1. Isotonic Solution

An isotonic solution has the same solute concentration as the potato’s cells, so there is no net water movement, and the mass change (\( \Delta m \)) is near zero.

• Let the initial mass be \( m_0 \). For a solution, \( \Delta m = m_{\text{final}} - m_0 \).
• If \( \Delta m \approx 0 \), the solution is isotonic. From the table (assuming the “change in mass” for one solution is ~0, e.g., if Lemon Juice has \( +0.3 \, \text{g} \), Sugar Water \( -3.6 \, \text{g} \), and Distilled Water \( +5 \, \text{g} \) – wait, the table’s “change in mass” is partially visible. Correcting: Isotonic means no net mass change (or minimal). If one solution’s \( \Delta m \) is closest to 0, that’s isotonic. For example, if Lemon Juice has \( +0.3 \, \text{g} \) (small change), it might be isotonic (but need precise data).

2. Hypotonic Solution

A hypotonic solution has a lower solute concentration than the potato’s cells, so water enters the cells, increasing mass (\( \Delta m > 0 \)).

• From the table, Distilled Water has \( +5 \, \text{g} \) (mass increases), so it’s hypotonic (water moves into the potato, causing mass gain).

Final Answers (Assuming Table Data):

1. Isotonic Solution: Lemon Juice (if \( \Delta m \approx 0 \), e.g., \( +0.3 \, \text{g} \) is small). Reason: Minimal mass change (no net water movement, equal solute concentration).
2. Hypotonic Solution: Distilled Water. Reason: Mass increases (\( +5 \, \text{g} \)), so water enters the potato (lower solute concentration in solution than in cells).

(Note: The exact answer depends on the full table’s “change in mass” values. The key is:

• Isotonic: \( \Delta m \approx 0 \) (no net water movement).
• Hypotonic: \( \Delta m > 0 \) (water enters cells, mass increases).)
