Explanation:
(1)What physical properties did you use to help you separate each mixture?
Mixture of salt and sand was separated using the physical properties of solubility
nails, toothpicks, and plastic mixers mixtures was separated based on magnetism and density differences.
Physical properties of a substance suggests everything that is happening to it when change is occurring to its constituents.
Such properties are observed with our senses or instruments.
In this experiment, solubility of the salt in the water solution was used in separating the mixture. Salt is a polar compound and it will readily dissolve in water.
Magnetism was first used to separate the metal from the non-metals then density differences between the mixer and toothpick was used to separate them.
(2)Could you have used other properties
I don't think there is any other physical property that will separate the mixtures perfectly well like this.
(3) Are these mixtures homogeneous or heterogeneous? Why?
The mixtures are homogeneous.
Homogeneous mixtures are mixtures that have their constituents existing in just a single phase.
Sand and salt are both solids and this is a single phase.
Toothpick, nails and plastic mixer are all solids existing in a single phase.
4)What are different types of mixtures, and how do they differ?
Mixtures can be divided into two based on the number of their phases:
Homogeneous mixtures are mixtures that exists in one single phase.:
Examples are:
- Gas - Gas mixtures
- Liquid - Liquid mixtures
- Solid - Solid mixtures
Heterogeneous mixtures are mixtures that exists in more than one phase.
- Gas - liquid mixtures
- Liquid - solid mixtures
- Gas - solid mixtures
