Question
Any acid that dissociates 100% into ions is called a_____.
- Strong base
- Strong acid
- Weak acid
- Weak base
Hint:
The strength of any acid is based on its dissociation power; i.e. the more hydrogen ions there are in a given volume, the stronger the acid.
The correct answer is: Strong acid
Any acid that dissociates 100% into ions is called a strong acid.
- Acids are substances that emit hydrogen ions into the surrounding medium of the solution, and the hydrogen ions are what give acids their acidic nature.
- Any acid's strength is based on its dissociation power; that is, the more hydrogen ions there are in a given volume, the stronger the acid.
- As a result, more hydrogen ions are released by stronger acids than weaker acids that only undergo partial dissociation, leaving just a little amount of hydrogen ions available. This is because stronger acids undergo complete dissociation.
- As a result, acids that totally dissociate into ions are known as strong acids, and acids that partially dissociate into ions are known as weak acids.
- Examples of strong acids include: HCl, H2SO4 & weak acids includes: HCOOH, CH3COOH
