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:**
Calculate the pH of a 0.300 M solution of lactic acid, for which the Ka value is 1.40 x 10^-4.
**Options:**
- A. 8.67
- B. 5.33
- C. 11.81
- D. 2.19
- E. 6.48 x 10^-3
In answering this question, you will apply the concept of acid dissociation to determine the pH of the lactic acid solution. Lactic acid partially ionizes in solution, and the extent of this ionization is given by the acid dissociation constant (Ka). Use the formula for calculating pH in a weak acid solution:
\[ \text{pH} = -\log[\text{H}^+] \]
Where \( [\text{H}^+] \) is the concentration of hydrogen ions. Use the expression for Ka:
\[ K_a = \frac{[\text{H}^+][\text{A}^-]}{[\text{HA}]} \]
Assume \( [\text{H}^+] = x \), and solve for x, then plug it back into the pH formula.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F3a79012e-b061-4a32-ad4b-59adf9665231%2Ff30f0479-307a-47ec-bc30-3313c8d1b2f9%2Fhwadaem_processed.jpeg&w=3840&q=75)
