7.1 ionic vs covalent solutes with pHet intro to solutions

Ionic vs Covalent Solutes

​this is to be aligned with part 1 of the introduction to solutions pHet simuulation

There were two solutes that you worked with in the pHet simulation. The first one was ​

Drag and Drop

When ionic solutes dissolve they ​ dissociate into ions. The is due to the ​

attraction that occurs between the positive ​

atom in a water molecule and the attraction between the negative ​

Placeholder

and the partial positive ​

Placeholder

atom in a water molecule.
