How to Make Insoluble Salts: State Symbols, Solubility Rules, and Preparation

The video tutorial covers state symbols, solubility rules, reactions of salt solutions, and preparation of insoluble salts. It explains the significance of state symbols in chemical reactions, details solubility rules for various salts, and demonstrates how to predict the outcomes of mixing salt solutions. The tutorial also provides a step-by-step guide on preparing and isolating insoluble salts.

What does the state symbol 'aq' indicate in a chemical reaction?

• The substance is a gas.

• The substance is a solid.

• The substance is a liquid.

• The substance is dissolved in water.

Which of the following salts is always soluble?

• Calcium carbonate

• Silver chloride

• Sodium chloride

• Lead sulfate

Which ion combination will likely result in an insoluble salt?

• Ammonium and hydroxide

• Sodium and nitrate

• Potassium and chloride

• Lead and sulfate

What happens when copper chloride is mixed with potassium carbonate?

• Potassium chloride becomes insoluble.

• Copper carbonate precipitates out.

• Potassium carbonate forms a gas.

• Copper chloride remains dissolved.

In a reaction between lead nitrate and magnesium chloride, which product is insoluble?

• Lead nitrate

• Magnesium nitrate

• Magnesium chloride

• Lead chloride

What is the first step in preparing an insoluble salt from a reaction?

• Mixing the solutions

• Drying the precipitate

• Rinsing with distilled water

• Filtering the solution

Why is distilled water used to rinse the precipitate during preparation?

• To cool the solution

• To remove impurities

• To dissolve the precipitate

• To increase solubility

What is the purpose of using a drying oven in the preparation of insoluble salts?

• To dissolve the salt

• To change the salt's color

• To increase the reaction rate

• To remove excess water

Which of the following is NOT a step in preparing an insoluble salt?

• Drying the precipitate

• Heating the solution to boiling

• Filtering the precipitate

• Mixing solutions

What is the main takeaway regarding the solubility of salts containing sodium, potassium, or ammonium?

• They are exceptions to solubility rules.

• They are usually insoluble.

• They are always soluble.

• They form gases.
