Practice 3.6 Polarity

Front

What does it mean for water to be polar?

Back

It is a molecule with opposite charges on opposite ends.

Front

Which substance can water NOT dissolve?

Back

Oil.

Front

Why does ice float on water?

Back

Water expands when it freezes, making ice less dense than water.

Front

Which part of a water molecule has a negative charge?

Back

The Oxygen.

Front

What kind of molecule is water?

Back

Polar Covalent.

Front

What is polarity in molecules?

Back

Polarity refers to the distribution of electrical charge over the atoms joined by the bond.

Front

What is a polar covalent bond?

Back

A type of bond where electrons are shared unequally between atoms, resulting in partial charges.

Front

What is the significance of hydrogen bonds in water?

Back

Hydrogen bonds contribute to water's unique properties, such as high surface tension and boiling point.

Front

How does the structure of water contribute to its polarity?

Back

Water's bent shape and the difference in electronegativity between oxygen and hydrogen create a dipole moment.

Front

What is the effect of water's polarity on its solvent properties?

Back

Water can dissolve many ionic and polar substances due to its ability to surround and separate charged particles.
