Dissolving Ammonium Nitrate Concepts

The video explains how to write the equation for ammonium nitrate (NH4NO3) dissolving in water (H2O). It begins by identifying NH4 and NO3 as ions with specific charges. The process of dissolving NH4NO3 in water is described, resulting in the formation of NH4+ and NO3- ions. The video concludes with the final equation, emphasizing the aqueous state of the ions.

What type of ions are NH4 and NO3?

• Metallic ions

• Monatomic ions

• Polyatomic ions

• Covalent ions

What is the charge on the ammonium ion (NH4)?

• Negative one

• Positive two

• Positive one

• Negative two

What happens to NH4NO3 when it is placed in water?

• It remains a solid

• It evaporates

• It forms a precipitate

• It dissolves into ions

Which ions are formed when NH4NO3 dissolves in water?

• NH4+ and NO3-

• NH3 and NO2

• NH2 and NO

• NH4- and NO3+

What does the 'aq' symbol indicate in a chemical equation?

• Aqueous or dissolved in water

• Liquid state

• Solid state

• Gaseous state

Why is water not written on the product side of the equation?

• Because it forms a solid

• Because the ions are aqueous

• Because it evaporates

• Because it is a reactant
