Answer:
Oxygen is the oxidizing agent and accept electrons
Explanation:
- Corrosion is an example of a redox reaction which involves both reduction and oxidation process.
- During corrosion a metal loses electrons and becomes oxidized to form a metal ion. Therefore, oxygen is the oxidizing agent since it undergoes reduction by gaining electrons.
- Therefore, during corrosion of iron, iron is the reducing agent and gives electrons, while oxygen is the oxidizing agent and accepts the electrons.
In a solution, when the concentrations of a weak acid and its conjugate base are equal: 1. the -log of the concentration of H+ and the -log of the Ka are equal.
<h3>What are Strong acid strong bases ?</h3>
Any acid that entirely ionises in solutions is considered a strong acid. When positioned, it emits the most hydrogen ions or protons.
- It is a substance with the capacity to take a proton out of an extremely weak acid. In water, they can also entirely separate into its ions. Examples include sodium hydroxide and potassium hydroxide (KOH) (NaOH)
<h3>What are weak acid and weak bases ?</h3>
Acids that don't entirely dissociate in solution are referred to as weak acids. In other words, any acid that is not a strong acid qualifies as a weak acid. The amount of dissociation determines how strong an acid is; the more dissociation, the stronger the acid.
- Weak bases are basic compounds that, when dissolved in solutions, do not entirely separate into their constituent ions.
