Ionic Equilibrium
Chemical equilibrium and ionic equilibrium are two major concepts in chemistry. Ionic equilibrium deals with the equilibrium involved in an ionization process while chemical equilibrium deals with the equilibrium during a chemical change. Ionic equilibrium is established between the ions and unionized species in a system. Understanding the concept of ionic equilibrium is very important to answer the questions related to certain chemical reactions in chemistry.
Arrhenius Acid
Arrhenius acid act as a good electrolyte as it dissociates to its respective ions in the aqueous solutions. Keeping it similar to the general acid properties, Arrhenius acid also neutralizes bases and turns litmus paper into red.
Bronsted Lowry Base In Inorganic Chemistry
Bronsted-Lowry base in inorganic chemistry is any chemical substance that can accept a proton from the other chemical substance it is reacting with.
![### Question 4 of 7:
**The oxidation number of Cl in HClO₄ is**
This section presents the fourth question in a series focused on determining oxidation numbers within chemical compounds. The task is to identify the oxidation number of chlorine (Cl) in the compound perchloric acid (HClO₄).
#### Explanation:
In perchloric acid (HClO₄), you need to consider the standard oxidation states of hydrogen and oxygen to determine the oxidation state of chlorine:
- Hydrogen (H) typically has an oxidation state of +1.
- Oxygen (O) typically has an oxidation state of -2. Since there are four oxygen atoms, their total contribution is -8.
To maintain neutrality in the molecule, the sum of oxidation numbers must be zero. Therefore, the equation for the oxidation states becomes:
\[ (+1) + x + 4(-2) = 0 \]
Solving for \( x \) gives the oxidation number of chlorine.
