Final answer:
Jorge's lemonade will become more sweet if he changes the water to lemon juice ratio from six to one to three to one, keeping the sugar constant because the concentration of lemon juice increases, making the flavor more potent.
Step-by-step explanation:
When Jorge changes the ratio of water to lemon juice in his lemonade from six to one to three to one, while keeping the amount of sugar constant, the lemonade will become more sweet. This is because the concentration of lemon juice increases, making it more potent compared to the amount of water, which dilutes sweetness. It's important to understand that sweetness is perceived because of the balance between the sourness of the lemon and the sugar added. A higher ratio of lemon juice means there will be a stronger lemon flavor, but since the sugar amount is unchanged, each sip of lemonade will taste sweeter since the dilution is less.
If we consider how solutions work in chemistry, when the ratio of solute (lemon juice) increases relative to the solvent (water), we end up with a more concentrated solution. In the provided lemonade scenario, the 'solute' is the lemon juice, and the 'solvent' is the water. A lower water to lemon juice ratio means each sip has more lemon juice in it, thus the sweetness will stand out more against the diluted solution, as there is less water to spread out the tastes.
