Solubility Rules: Predicting Solubility of Compounds in Water

The video tutorial explains how to determine if a salt compound is soluble or insoluble in water. It introduces state symbols used in chemical reactions and explains their significance. The tutorial covers solubility rules, detailing which salts are generally soluble or insoluble based on their ions. Practical examples are provided to illustrate how these rules are applied in chemical equations, helping viewers predict the solubility of different compounds.

What does the state symbol 'aq' indicate about a compound?

• It is a liquid.

• It is a gas.

• It is dissolved in water.

• It is a solid.

Which of the following salts is generally soluble?

• Calcium carbonate

• Lead sulfate

• Sodium nitrate

• Silver chloride

Which ion's presence in a salt generally indicates it will be soluble?

• Lead

• Silver

• Potassium

• Barium

Which of the following is an exception to the insolubility of carbonates?

• Calcium carbonate

• Sodium carbonate

• Iron carbonate

• Magnesium carbonate

What is the solubility status of calcium hydroxide?

• Not applicable

• Highly soluble

• Slightly soluble

• Insoluble

When mixing lead nitrate and magnesium chloride, which compound forms a precipitate?

• Magnesium chloride

• Lead nitrate

• Magnesium nitrate

• Lead chloride

What happens to ions when two aqueous solutions are mixed?

• They remain unchanged.

• They form a single compound.

• They swap partners to form new compounds.

• They evaporate.
