Procedure: Fill two containers about half full of cold tap water. In the first container stir in enough table salt to saturate the solution, leaving some excess salt undissolved. In the second container stir in the same amount of table sugar. If excess does not remain, add more solid to each container. In the third container pour an equal amount of carbonated beverage. In this solution we will be observing the dissolved gas, carbon dioxide (CO2). Place all three open containers in a pot of water and gently heat until the water boils. Occasionally stir each container's contents. CAUTION: Steam contains much energy and can rapidly damage skin. Be careful not to spill hot water potentially causing skin damage. Note and record any change in the amount of solid undissolved in the first two containers. Observe any bubbles forced out of the solution during the heating of the beverage. Record your observations in the table below. (Select yes or no and more undisoolved or less or no change) CONTAINER 1: water + table salt--Observation of bubbles out of the solution: Yes or No? Change in amount of solid undissolved: More undissolved solid or Less undissolved solid or No change. CONTAINER 2: water + table sugar--Observation of bubbles out of the solution: Yes or No? Change in amount of solid undissolved: More undissolved solid or Less undissolved solid or No change. CONTAINER 3: carbonated beverage--Observation of bubbles out of the solution: Yes or No? Change in amount of solid undissolved: N/A
Temperature Effect on Solubility (hands-on experiment to do at home)
Procedure:
- Fill two containers about half full of cold tap water.
- In the first container stir in enough table salt to saturate the solution, leaving some excess salt undissolved.
- In the second container stir in the same amount of table sugar. If excess does not remain, add more solid to each container.
- In the third container pour an equal amount of carbonated beverage. In this solution we will be observing the dissolved gas, carbon dioxide (CO2).
- Place all three open containers in a pot of water and gently heat until the water boils. Occasionally stir each container's contents. CAUTION: Steam contains much energy and can rapidly damage skin. Be careful not to spill hot water potentially causing skin damage.
Note and record any change in the amount of solid undissolved in the first two containers. Observe any bubbles forced out of the solution during the heating of the beverage. Record your observations in the table below.
(Select yes or no and more undisoolved or less or no change)
CONTAINER 1: water + table salt--Observation of bubbles out of the solution: Yes or No? Change in amount of solid undissolved: More undissolved solid or Less undissolved solid or No change.
CONTAINER 2: water + table sugar--Observation of bubbles out of the solution: Yes or No? Change in amount of solid undissolved: More undissolved solid or Less undissolved solid or No change.
CONTAINER 3: carbonated beverage--Observation of bubbles out of the solution: Yes or No? Change in amount of solid undissolved: N/A
