Solubility of Sodium Fluoride

The video tutorial explores the solubility of sodium fluoride (NaF) in water. It begins by discussing the solubility rules, highlighting that group one elements like sodium are generally soluble. The tutorial then uses a solubility table to confirm that NaF is indeed soluble in water, breaking into Na+ and F- ions. The video concludes with a summary of these findings.

What does the solubility rule for group one elements imply about sodium fluoride?

• It is insoluble in water.

• It is soluble in water.

• It reacts with water.

• It forms a precipitate.

What ions are formed when sodium fluoride dissolves in water?

• Na+ and Cl-

• Na2+ and F2-

• Na+ and F-

• Na- and F+

How can we verify the solubility of sodium fluoride?

• By checking a solubility table.

• By observing its color change.

• By measuring its pH.

• By heating it.

What does the 'S' in the solubility table indicate for sodium fluoride?

• It is slightly soluble.

• It is soluble.

• It is supersaturated.

• It is insoluble.
