Question

1. theme patterns look at the recipe above. fill out the table to describe the solvent(s) and solute(s) for the lemonade, which is an aqueous solution.

1. suppose you want to make the lemonade sweeter. describe how you would change the concentration of the solution. what solute or solvent would you add?

sep plan an investigation you want to find out the quickest way to dissolve salt in water by changing temperature, surface area of the solute, or agitating. plan an investigation that will help you determine how to increase the rate of dissolution.

Explanation:

Step1: Identify solvent and solutes in lemonade

In an aqueous solution like lemonade, water is the solvent. Solutes include lemon - juice (acids, flavor compounds), sugar (sweetness), and any added flavorings or salts.

Step2: Make lemonade sweeter

To make lemonade sweeter, we need to increase the amount of the sweet - tasting solute. Sugar is the common sweet - tasting solute in lemonade, so we would add sugar.

Step3: Plan salt dissolution investigation

1. Temperature: Prepare three beakers with the same amount of water. One with cold water, one with room - temperature water, and one with hot water. Add the same amount of salt to each beaker simultaneously and start a timer. Record the time it takes for the salt to dissolve completely in each beaker.
2. Surface area: Take two equal amounts of salt. Leave one as large crystals and crush the other into fine powder. Add them to two beakers with the same amount of water at the same temperature. Start a timer and record the time for each to dissolve.
3. Agitation: Take two beakers with the same amount of water and salt. Agitate one beaker (stir with a stirrer or shake) and leave the other still. Record the time it takes for the salt to dissolve in each beaker.

Answer:

1. Solvent: Water; Solutes: Lemon - juice, sugar, flavorings (if any)
2. Add sugar (a solute)
3. See above plan for investigating the rate of salt dissolution in water by changing temperature, surface area, and agitation.
