Construct the expression for Ka for the weak acid, CH:COOH. CH:COOH(aq) + H2O(1) = H:O*(aq) + CH:COO-(aq) 1 Based on the definition of Ka, drag the tiles to construct the expression for the given acid. Ka
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.
![### Constructing the Acid Dissociation Constant Expression for CH₃COOH
In this exercise, we will derive the expression for the acid dissociation constant (\(K_a\)) of the weak acid acetic acid, \(CH₃COOH\).
#### Reaction Equation
The dissociation reaction for acetic acid is given by:
\[ CH₃COOH(aq) + H₂O(l) \rightleftharpoons H₃O^+(aq) + CH₃COO^-(aq) \]
#### Task
We need to construct the expression for \(K_a\) using the reaction equation above.
#### Instructions
Based on the definition of \(K_a\), drag the appropriate tiles to construct the expression for the given acid. \(K_a\) is defined by the formula:
\[ K_a = \frac{[H₃O^+][CH₃COO^-]}{[CH₃COOH]} \]
Below the reaction equation, you will find draggable tiles representing different molecules and ions, including their concentrations or squared terms (e.g., \([H₂O]\), \([H₃O^+]\), \([OH^-]\), \([CH₃COOH]\), etc.).
#### Diagram
- The diagram contains a progress bar indicating the construction process, with a reset button to start over if needed.
- Beneath the input boxes, draggable tiles are available to complete the expression. These tiles can include:
- Ion concentrations: \([H₂O]\), \([H₃O^+]\), \([OH^-]\)
- Acid/base concentrations: \([CH₃COOH]\), \([CH₃COO^-]\)
- Squared concentrations: \([H₂O]^2\), \([H₃O^+]^2\), etc.
By dragging the correct tiles into the two blank slots beside \(K_a =\), you complete the expression correctly.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F884ae86d-1520-453b-9fec-2538b1a8b912%2Fb02f4fcc-811c-422f-b6b9-642ecc82717b%2F7tbzd8_processed.png&w=3840&q=75)
