Solubility of Ammonium Carbonate

The video tutorial discusses the solubility of ammonium carbonate (NH4)2CO3 in water. It explains three methods to determine solubility: memorizing solubility rules, using a solubility chart, and conducting a practical test. The video concludes that ammonium carbonate is soluble in water, as confirmed by the solubility rules and chart, and by observing its dissolution in water.

What is the first method mentioned to determine the solubility of ammonium carbonate?

• Memorizing solubility rules

• Measuring temperature change

• Using a pH meter

• Observing color change

According to the solubility rules, which ion indicates that ammonium carbonate is soluble?

• Sulfate ion

• Carbonate ion

• Ammonium ion

• Nitrate ion

What does the 'S' represent in the solubility chart when checking ammonium carbonate?

• Solid

• Suspended

• Soluble

• Slightly soluble

Where are the positive ions located on the solubility chart?

• On the bottom

• On the left

• In the center

• On the right

What happens to ammonium carbonate when it is dissolved in water?

• It remains unchanged

• It changes color

• It dissociates into ions

• It forms a precipitate

Which ions are formed when ammonium carbonate dissociates in water?

• Ammonium and sulfate ions

• Carbonate and nitrate ions

• Ammonium and carbonate ions

• Sulfate and nitrate ions

What is the final method to determine the solubility of ammonium carbonate?

• Observing under UV light

• Measuring pH

• Conducting a practical test

• Using a microscope

What is the conclusion about the solubility of ammonium carbonate in water?
