What is solubility?

Back

Solubility is the ability of a substance (solute) to dissolve in a solvent (usually water) at a given temperature and pressure.

Front

Which salt decreases in solubility as temperature increases?

Back

Ce₂(SO₄)₃ is the salt that decreases in solubility as temperature increases.

Front

What is an ionic compound?

Back

An ionic compound is a chemical compound composed of ions held together by electrostatic forces termed ionic bonding. Example: FeO.

Front

What is atomic radius?

Back

Atomic radius is the distance from the nucleus of an atom to the outermost shell of electrons.

Front

Which element has the largest atomic radius among Na, Mg, Al, and Cl?

Back

Sodium (Na) has the largest atomic radius.

Front

Which element has the largest atomic radius among He, Ne, Rn, and Ar?

Back

Radon (Rn) has the largest atomic radius.

Front

What is a characteristic of alkali metals?

Back

Alkali metals are highly reactive with water.

Front

What is the trend of solubility of most salts in water as temperature increases?

Back

Most salts increase in solubility as temperature increases.

Front

What is the general formula for ionic compounds?

Back

Ionic compounds are generally formed from a metal and a non-metal, resulting in a formula like MX, where M is a metal and X is a non-metal.

Front

What is electronegativity?

Back

Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons.
