Question
The strength of the acid is given by:
- The number of hydrogen ions released when it is dissolved in the water.
- The number of hydrogen atoms formed in water
- Both A and B
- The number of hydroxyl ions released in water
Hint:
Acids release hydrogen ions when dissolved in water.
The correct answer is: The number of hydrogen ions released when it is dissolved in the water.
An acid is a molecule or ion capable of either donating a proton (i.e. hydrogen ion, H + ), known as a Bronsted–Lowry acid, or forming a covalent bond with an electron pair, known as a Lewis acid. The first category of acids are the proton donors, or Bronsted–Lowry acids. In the special case of aqueous solutions, proton donors form the hydronium ion H3O + and are known as Arrhenius acids.
The strength of the acid is given by the number of hydrogen ions released when it is dissolved in the water.
