Solubility and Ionic Compounds Concepts

This video tutorial explains the reaction between lead(II) chloride (PbCl2) and water (H2O). It covers the nature of ionic compounds, their solubility, and how to use a solubility table to determine the solubility of PbCl2. The tutorial guides viewers through writing and balancing the chemical equation for the reaction, highlighting the formation of ions in an aqueous solution. The video concludes with a summary of the reaction and its slightly soluble nature.

What type of compound is formed when a metal reacts with a non-metal?

• Organic compound

• Metallic compound

• Ionic compound

• Covalent compound

Why is it important to check a solubility table for ionic compounds?

• To check if they are soluble in water

• To know their color

• To find the boiling point

• To determine the melting point

What does 'ss' indicate in a solubility table?

• Super soluble

• Slightly soluble

• Solid state

• Soluble solution

What ions are formed when PbCl2 dissolves in water?

• Pb2+ and Cl-

• Pb+ and Cl2-

• Pb2+ and Cl2-

• Pb+ and Cl-

How many chloride ions are needed to balance the charge of one lead ion in PbCl2?

• One

• Two

• Four

• Three

What is the charge on the lead ion in PbCl2?

• +1

• +2

• -1

• -2

What does 'aq' signify when written after an ion in a chemical equation?

• Aqueous or solid in water

• Aqueous or dissolved in water

• Aqueous or gaseous in water

• Aqueous or liquid in water

Why is it unnecessary to write H2O on the product side of the equation?

• Because it is a reactant

• Because it evaporates

• Because the ions are dissolved in water

• Because it is not involved in the reaction

What remains in the container after PbCl2 is added to water?

• Only dissolved ions

• Only water

• Only solid PbCl2

• Both dissolved ions and solid PbCl2

What is the primary focus of the video tutorial?

• The uses of chlorine

• The history of lead compounds

• The reaction of lead(II) chloride with water

• The properties of water
