Calculate Concentration of One Component





Formula

The formula to calculate the concentration of one component is:

\[ R = \frac{C1}{C2} \]

Where:

Example

Let's say the component ratio is 2, the concentration of component 1 is 4, and the concentration of component 2 is 2. Using the formula:

\[ R = \frac{4}{2} \]

We get:

\[ R = 2 \]

So, the component ratio (\( R \)) is 2.

How to Calculate Buffer Ratio from pH

Definition: The buffer ratio is the ratio of the concentration of the conjugate base to the concentration of the weak acid in a buffer solution.

Formula: \( \text{Buffer Ratio} = 10^{(\text{pH} - \text{pKa})} \)

Example: \( \text{Buffer Ratio} = 10^{(7.4 - 6.8)} \)

Calculation of Buffer Solution

Definition: Calculating a buffer solution involves determining the concentrations of the acid and its conjugate base to achieve a desired pH.

Formula: \( \text{pH} = \text{pKa} + \log \left( \frac{[\text{A}^-]}{[\text{HA}]} \right) \)

Example: \( \text{pH} = 4.75 + \log \left( \frac{0.1}{0.2} \right) \)

How to Calculate Buffer Capacity

Definition: Buffer capacity is a measure of the efficiency of a buffer in resisting changes in pH upon the addition of an acid or base.

Formula: \( \beta = \frac{\Delta B}{\Delta \text{pH}} \)

Example: \( \beta = \frac{0.01}{0.2} \)

Formula of Buffer Capacity

Definition: The formula of buffer capacity quantifies the ability of a buffer solution to resist changes in pH.

Formula: \( \beta = 2.303 \left( \frac{C_a K_a [\text{HA}]}{(K_a + [\text{H}^+])^2} \right) \)

Example: \( \beta = 2.303 \left( \frac{0.1 \times 1.8 \times 10^{-5} \times 0.1}{(1.8 \times 10^{-5} + 1 \times 10^{-7})^2} \right) \)
