公式
## How to Calculate Neutralization Volume ### Formula **V_b = (C_a × V_a) / C_b** Where: - **V_b** = volume of base required (mL) - **C_a** = concentration of acid (M) - **V_a** = volume of acid (mL) - **C_b** = concentration of base (M) This applies to monoprotic 1:1 neutralization. For polyprotic acids, multiply by the number of acidic protons.
计算示例
Neutralize 50 mL of 0.1 M HCl with 0.1 M NaOH.
- 01V_b = (C_a × V_a) / C_b
- 02V_b = (0.1 × 50) / 0.1
- 03V_b = 5 / 0.1
- 04V_b = 50 mL
常见问题
What is neutralization?
Neutralization is a reaction between an acid and a base that produces water and a salt. For strong acids and bases, the reaction goes to completion.
Is neutralization always exothermic?
Yes, strong acid-strong base neutralization releases about 57.1 kJ/mol of water formed. Weak acid or base reactions release less due to partial dissociation.
What happens if I add excess base?
The solution becomes basic (pH > 7). The excess hydroxide ions remain in solution.
