Can a substance be classified as ionic or molecular on the basis of whether or not it dissolves in water?

Physical and chemical properties can be used to classify a substance as ionic or molecular. Ionic compounds are those consisting of cations and anions which are bonded to each other by electrostatic attractions. ... When molecular compounds do dissolve in water, they do not conduct electricity.

Can a substance be identified as ionic or molecular based on conductivity of a solution?

If a compound cannot conduct electricity in its solid or liquid state, it is covalent. If a compound does conduct electricity when dissolved in solution or molten, it is an ionic compound.

How can a substance be classified as ionic or molecular?

Ionic compounds usually form hard crystalline solids with high melting points. Covalent molecular compounds, in contrast, consist of discrete molecules held together by weak intermolecular forces and can be gases, liquids, or solids at room temperature and pressure.

Can a substance be classified molecular?

Figure 1.11 Depending on its properties, a given substance can be classified as a homogeneous mixture, a heterogeneous mixture, a compound, or an element.

How do you know if a substance is ionic?

One way would be to dissolve them in water. Ionic compounds will break into ions and allow the solution to conduct an electric current, whereas covalently bonded substances will not. Another way would be to find the substance's melting point. Ionically bonded compounds have much higher melting points.

How do you know if a substance is conductive?

The easiest way to determine whether a compound can conduct a current is to identify its molecular structure or composition. Compounds with strong conductivity dissociate completely into charged atoms or molecules, or ions, when dissolved in water. These ions can move and carry a current effectively.

How do you know if a substance conducts electricity?

Materials conduct electricity if one of two things happens: If electrons can move around freely (as in the delocalized bonds of metals), then electricity can be conducted. If ions can move around freely, electricity can be conducted.

Which is a molecular substance?

Definition of Molecular Substances

It's a molecular substance, which is a substance with two or more atoms, the smallest units of matter, joined together by a covalent bond. A covalent bond is the link created through the sharing of electrons that holds these atoms together.

How do you identify a molecular compound?

A molecular compound is usually composed of two or more nonmetal elements. Molecular compounds are named with the first element first and then the second element by using the stem of the element name plus the suffix -ide. Numerical prefixes are used to specify the number of atoms in a molecule.

Why is it important to know if a substance is a molecular compound or an ionic compound before predicting its effect on the boiling and freezing points of a solvent?

Why is it important to know if a substance is a molecular compound or an ionic compound before predicting its effect on the boiling and freezing points of a solvent? ... Molecular compounds dissociate easier than ionic compounds, thereby having a greater effect on the b.p. and f.p.

How will you know if a substance is an element?

A substance that cannot be broken down into chemically simpler components is an element. Aluminum, which is used in soda cans, is an element. A substance that can be broken down into chemically simpler components (because it has more than one element) is a compound.

Which substance is an ionic compound?

Ionic Compounds Are Balanced

Table salt is an example of an ionic compound. Sodium and chlorine ions come together to form sodium chloride, or NaCl. The sodium atom in this compound loses an electron to become Na+, while the chlorine atom gains an electron to become Cl-.
