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:**
Which one of these salts will form a **basic** solution upon dissolving in water?
**Options:**
- [ ] KBr
- [ ] NaCl
- [ ] NaNO₂
- [ ] NH₄NO₃
**Detailed Explanation:**
In this question, we are asked to determine which salt forms a basic solution when dissolved in water. To understand this, we must consider the behavior of the ions that make up each salt when they interact with water.
1. **KBr (Potassium Bromide):**
- Dissociation: KBr → K⁺ + Br⁻
- Effect on pH: Potassium ion (K⁺) is a neutral ion from a strong base (KOH), and Bromide ion (Br⁻) is a neutral ion from a strong acid (HBr). The solution remains neutral.
2. **NaCl (Sodium Chloride):**
- Dissociation: NaCl → Na⁺ + Cl⁻
- Effect on pH: Sodium ion (Na⁺) is neutral from a strong base (NaOH), and Chloride ion (Cl⁻) is neutral from a strong acid (HCl). The solution remains neutral.
3. **NaNO₂ (Sodium Nitrite):**
- Dissociation: NaNO₂ → Na⁺ + NO₂⁻
- Effect on pH: Sodium ion (Na⁺) is neutral from a strong base (NaOH), and Nitrite ion (NO₂⁻) comes from a weak acid (HNO₂). NO₂⁻ can accept a proton (H⁺) from water, forming HNO₂ and OH⁻, which makes the solution basic.
4. **NH₄NO₃ (Ammonium Nitrate):**
- Dissociation: NH₄NO₃ → NH₄⁺ + NO₃⁻
- Effect on pH: Ammonium ion (NH₄⁺) comes from a weak base (NH₃) and acts as a weak acid, while Nitrate ion (NO₃⁻) is neutral from a strong acid (HNO₃). The solution can become slightly acidic due to the presence of NH₄⁺.
