Solubility of Phosphates and Compounds

The video tutorial explains the solubility of silver phosphate (Ag3PO4) in water, concluding it is insoluble. It discusses three methods to determine this: memorizing solubility rules, using a solubility chart, and practical testing by adding the compound to water. The video emphasizes that while a small amount may dissolve, it is generally considered insoluble. Dr. B. guides viewers through each method, reinforcing the concept with visual aids and practical examples.

What is the solubility status of Ag3PO4 in water?

• Soluble

• Partially soluble

• Highly soluble

• Insoluble

According to solubility rules, which of the following is true about most phosphates?

• They dissolve completely.

• They are soluble in water.

• They are always exceptions.

• They are insoluble in water.

How can a solubility chart help determine the solubility of a compound?

• By displaying the interaction between positive and negative ions.

• By showing the melting point of the compound.

• By listing the pH level of the compound.

• By indicating the boiling point of the compound.

What does the 'I' on the solubility chart indicate for silver phosphate?

• It is highly reactive.

• It is partially soluble.

• It is insoluble.

• It is soluble.

What is the expected outcome when silver phosphate is added to water based on the solubility chart and rules?

• It will dissolve completely.

• It will remain mostly undissolved.

• It will react violently.

• It will change color.
