(a)
Interpretation: Food coloring needs to be classified as a homogeneous or heterogeneous mixture.
Concept Introduction: A mixture is said to be homogenous when its composition is uniform throughout whereas a mixture is said to be heterogenous when its composition is not uniform throughout.
(a)
Answer to Problem 15LC
Homogeneous mixture.
Explanation of Solution
The composition in the entire mixture of food coloring is uniform throughout so it is said to be a homogenous mixture.
(b)
Interpretation: Ice cubes in liquid water need to be classified as a homogeneous or heterogeneous mixture.
Concept Introduction: A mixture is said to be homogenous when its composition is uniform throughout whereas a mixture is said to be heterogenous when its composition is not uniform throughout.
(b)
Answer to Problem 15LC
Heterogeneous mixture.
Explanation of Solution
The composition in the entire mixture of ice cubes in liquid water is not uniform throughout so it is said to be a heterogeneous mixture.
(c)
Interpretation: Mouthwash needs to be classified as a homogeneous or heterogeneous mixture.
Concept Introduction: A mixture is said to be homogenous when its composition is uniform throughout whereas a mixture is said to be heterogenous when its composition is not uniform throughout.
(c)
Answer to Problem 15LC
Homogeneous mixture.
Explanation of Solution
The composition in the entire mixture of mouthwash is uniform throughout so it is said to be a homogenous mixture.
(d)
Interpretation: Mashed, unpeeled potatoes need to be classified as a homogeneous or heterogeneous mixture.
Concept Introduction: A mixture is said to be homogenous when its composition is uniform throughout whereas a mixture is said to be heterogenous when its composition is not uniform throughout.
(d)
Answer to Problem 15LC
Heterogeneous mixture.
Explanation of Solution
The composition in the entire mixture of the mashed, unpeeled potatoes is not uniform throughout so it is said to be a heterogeneous mixture.
