Question

students are asked to classify these substances based on their physical properties: table salt sugar baking soda epsom salt sort the properties to show whether they would help or not help the students to compare and identify the substances. conductivity in water color density magnetism mass solubility help not help

Explanation:

Step1: Analyze conductivity in water

Table - salt, baking - soda, and Epsom salt are ionic compounds and can conduct electricity in water, while sugar is a covalent compound and does not conduct well. So conductivity in water helps.

Step2: Analyze color

All of table - salt, sugar, baking - soda, and Epsom salt are white or color - less in their common forms. So color does not help.

Step3: Analyze density

Different substances have different densities. Measuring density can help distinguish between them. So density helps.

Step4: Analyze magnetism

None of table - salt, sugar, baking - soda, and Epsom salt are magnetic. So magnetism does not help.

Step5: Analyze mass

Mass alone is not a characteristic property as it depends on the amount of the substance. So mass does not help.

Step6: Analyze solubility

Table - salt, sugar, baking - soda, and Epsom salt have different solubilities in water at different temperatures. So solubility helps.
