Question

Consider these liquids.

Dishwashing detergent: 1.03 density g/mL

Maple syrup: 1.37 density g/mL

Vegetable oil: 0.91 g/mL

a. if you pour equal volumes of these three liquids into a 250 milliliter graduated cylinder, in what order will you add the liquids to create three separate layers? Explain your reasoning.

b. If a liquid were poured into the cylinder and it formed the layer that was on the bottom of the other three layers, what can you tell about one of the properties of this liquid?

c. what would happen if a volume of water equal to the other liquids report into the cylinder and part A and then the contents were mixed vigorously? Please explain.

Answer 1

a. Maple syrup will slowly dissolve in dishwashing liquid and vegetable oil may be slightly soluble in the detergent. So, by slowly mixing the liquids we may stop them from mixing with each other. When you pour liquids with different densities into a container, the liquid with higher density occupais lower part. You have to add the heavier liquid(higer density liquid first) then the lesser one and the later the least, so that the layer are not disturbed. And three seprate layers could be formed.

ORDER: Maple syrup, Dishwashing detergent, Vegetable oil.

b. As said, heavier liquid occupaies the bottom. So, we could say that the liquid that's added has more density than the three liquids. From which we can simply say that its density is greater than the 1.37 density g/mL (Maple syrup).

c.   After vigorous stirring, a cloudy emulsion will likely form. At least some of the maple syrup and dishwashing detergent should dissolve in the water layer, but eventually the vegetable oil layer may separate out and rise to the top of the mixture.
