Question

part a
complete these steps for each material listed in the table. record your findings in the table.

1. describe the appearance of the material. include its color and state (solid or liquid).
2. pour ¼ cup of water into a small, clear container. measure ¼ teaspoon of the material, and carefully pour it into the container. look at the side of the container as you pour in the material. decide whether the material is less dense or more dense than water by observing whether the material floats or sinks.
3. swirl the container to see whether the material mixes with the water.
4. rinse and dry the container and the measuring spoon after each use.

material appearance of the material, including its color and state is the material less dense or more dense than water? does the material dissolve in (mix with) water?
baking soda
baking powder
salt
sugar
white flour
white vinegar
oil (any kind)

Explanation:

Step1: Describe baking soda

White solid

Step2: Determine density of baking soda

More dense than water (sinks)

Step3: Check dissolution of baking soda

Dissolves in water

Step4: Describe baking powder

White solid

Step5: Determine density of baking powder

More dense than water (sinks)

Step6: Check dissolution of baking powder

Dissolves in water

Step7: Describe salt

White solid

Step8: Determine density of salt

More dense than water (sinks)

Step9: Check dissolution of salt

Dissolves in water

Step10: Describe sugar

White solid

Step11: Determine density of sugar

More dense than water (sinks)

Step12: Check dissolution of sugar

Dissolves in water

Step13: Describe white flour

White solid

Step14: Determine density of white flour

More dense than water (sinks)

Step15: Check dissolution of white flour

Does not dissolve in water (forms a suspension)

Step16: Describe white vinegar

Color -less liquid

Step17: Determine density of white vinegar

Less dense than water (mixes uniformly, but density is close to water's; for the purpose of this experiment, we can consider it less dense as it doesn't sink)

Step18: Check dissolution of white vinegar

Dissolves in water

Step19: Describe oil

Color - varies (usually yellow - ish or clear), liquid

Step20: Determine density of oil

Less dense than water (floats)

Step21: Check dissolution of oil

Does not dissolve in water

Answer:

Material	Appearance of the material, including its color and state	Is the material less dense or more dense than water?	Does the material dissolve in (mix with) water?
baking powder	White solid	More dense	Yes
salt	White solid	More dense	Yes
sugar	White solid	More dense	Yes
white flour	White solid	More dense	No
white vinegar	Color - less liquid	Less dense	Yes
oil (any kind)	Color - varies (usually yellow - ish or clear), liquid	Less dense	No
