Question 7 • AA-F26 Physical Science

Which property of table salt is also a property of other ionic compounds?

Answer
A
has a low melting point
B
does not dissolve in water
C
forms crystal structures
D
does not conduct electricity

Explanation

Ionic compounds are made of positively and negatively charged ions arranged in a repeating pattern, so they commonly form crystal structures. Table salt, sodium chloride, is one example. Ionic compounds generally have high melting points, and whether they dissolve in water or conduct electricity depends on the compound and its state.
