Stoichiometric Equivalence Derivation
Moles of H⁺ neutralized must equal moles of OH⁻ added:
$V_b = \frac{M_a \times V_a \times n_a}{M_b \times n_b} = \frac{0.1 \times 25 \times 1}{0.1 \times 1} = 25.00\text{ mL}$
What is Acid-Base Titration?
Titration is an analytical technique to determine the unknown concentration of an identified analyte using a standardized titrant.
Formula & Step-by-Step Calculation
M_a × V_a × n_a = M_b × V_b × n_b
Equivalence of moles of H⁺ and moles of OH⁻.
Worked Step-by-Step Examples
Example 1
Titrating 25 mL of 0.1 M HCl with 0.2 M NaOH
Solution: V_b = 12.50 mL of NaOH required
• (0.1 × 25 × 1) / (0.2 × 1) = 12.5 mL
