A) Reaction between acids and reactive metals
- Strong acids can react with reactive metal faster and more vigorously. More hydrogen gas produced at a faster rate.
- Weak acids can react with reactive metal slower and less vigorously. Less hydrogen gas produced at a slower rate.
Weak or Strong
|water, H2O||no light||weak||molecules|
|hydrochloric acid, HCl||bright||strong||ions|
|acetic acid, HC2H3O2||dim||weak||mostly molecules, less ions|
- Strong acids able to conduct electricity better as shown in hydrochloric acid because it contains a large number of freely moving ions as strong acids dissociate completely in water.
- Weak acids conduct electricity weakly as shown in acetic acid because it contains a few number of moving ions as weak acids dissociate partially in water. Most of weak acids still remain in covalent molecule.
