Mastering Solubility Rules and Net Ionic Equations Through Lab Experiments

The video tutorial guides students through a lab on solubility rules, focusing on creating a solubility rules table, understanding double replacement reactions, and writing net ionic equations. The instructor demonstrates mixing various anions and cations to observe reactions, identifying precipitates, and determining solubility. Students are instructed to record observations and create their own solubility rules table based on the lab results.

What is the primary goal of the Solubility Rules lab?

• To learn about redox reactions

• To create a solubility rules table

• To study the properties of gases

• To understand acid-base titrations

What indicates a reaction has occurred when mixing two solutions?

• The solution evaporates

• The solution becomes cloudy

• The solution remains clear

• The solution changes color

What does a clear solution indicate after mixing sodium fluoride and silver ion?

• A precipitate has formed

• Silver fluoride is insoluble

• Silver fluoride is soluble

• A redox reaction has occurred

What should you record when a precipitate forms?

• The pH of the solution

• The color of the precipitate

• The volume of the solution

• The temperature of the solution

Which ion did not form a precipitate with the silver ion?

• Iodide ion

• Carbonate ion

• Fluoride ion

• Chloride ion

What is the solubility status of calcium fluoride?

• Highly insoluble

• Highly soluble

• Insoluble

• Slightly soluble

Which cation did not form any precipitates with the anions?

• Zinc
