Concept explainers

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.

### Titrations and pH Curves

**Graph Description:**
The graph depicts a titration curve with pH on the y-axis and volume added on the x-axis. The curve has an initial pH of about 0, rises steeply around the equivalence point, and then levels off at a higher pH, likely indicating a strong acid-strong base titration.

**4. Which of the following titrations could the following curve describe?**
- a. $ \text{KOH} $ added to $ \text{HNO}_3 $
- b. $ \text{HCl} $ added to aqueous $ \text{NH}_3 $
- c. $ \text{HNO}_3 $ added to $ \text{KOH} $
- d. $ \text{LiOH} $ added to $ \text{CH}_3\text{COOH} $
- e. $ \text{CH}_3\text{COOH} $ added
