Chemistry Chapter 3

Post by mcat5122018 » Wed Apr 18, 2018 1:01 am

Hi,

During the single and double displacement reactions topics in the book, it mentioned that "Unlike in single displacements, however, both reactants usually begin and end as charged species within ionic compounds, as opposed to one solid metal and ionic form on each side." Can you explain what this means? I am confused by this statement.

The way I understood this was that in single displacement reactions, the reactants will be a solid metal and an ionic compound, but in double displacement reactions, the reactants will have two ionic compounds.

Thank you.

Hi mcat5122018,

Sorry that the phrasing was difficult to follow! But you've got the idea. In double displacement reactions, the ions basically swap places, and no single-element substance is formed. Thanks for checking in!
