「滴定计算器(求未知浓度)」是什么?What is the Titration Calculator tool?
根据酸碱滴定的终点数据计算未知溶液的浓度:n₁·C₁·V₁ = n₂·C₂·V₂,可填写每摩尔待测物消耗的滴定剂摩尔数(如 NaOH 滴定 H₂SO₄ 填 2),体积可用 mL 或 L。Work out the concentration of an unknown solution from titration end-point data using n₁·C₁·V₁ = n₂·C₂·V₂, with the moles of titrant per mole of analyte (e.g. 2 for NaOH titrating H₂SO₄) and volumes in mL or L.
如何使用「滴定计算器(求未知浓度)」?How do I use the Titration Calculator tool?
在「滴定计算器(求未知浓度)」中,填写「滴定剂浓度 C₁(mol/L)」、「滴定剂消耗体积 V₁」、「待测液体积 V₂」、「体积单位」、「每摩尔待测物消耗的滴定剂摩尔数」等参数,结果会随输入实时计算并显示在下方。In the Titration Calculator: Fill in "Titrant concentration C₁ (mol/L)", "Titrant volume used V₁", "Analyte volume V₂", "Volume unit", "Moles of titrant per mole of analyte"; results are recalculated instantly as you type.
计算公式?What is the formula?
滴定剂物质的量 = C₁ × V₁;待测物物质的量 = 滴定剂物质的量 ÷ 每摩尔待测物消耗的滴定剂摩尔数;待测液浓度 C₂ = 待测物物质的量 ÷ V₂。Moles of titrant = C₁ × V₁; moles of analyte = moles of titrant ÷ moles of titrant per mole of analyte; C₂ = moles of analyte ÷ V₂.
「每摩尔待测物消耗的滴定剂摩尔数」怎么填?What do I enter for moles of titrant per mole of analyte?
填每 1 mol 待测物需要的滴定剂摩尔数。例如用 NaOH 滴定 HCl 填 1;用 NaOH 滴定 H₂SO₄ 填 2(H₂SO₄ + 2NaOH);用 HCl 滴定 Na₂CO₃(到第二终点)填 2。Enter moles of titrant needed per mole of analyte: NaOH titrating HCl is 1; NaOH titrating H₂SO₄ is 2 (H₂SO₄ + 2NaOH); HCl titrating Na₂CO₃ to the second end point is 2.
计算结果可以用于作业或工程吗?Can I use the results for homework or engineering?
「滴定计算器(求未知浓度)」使用教科书标准公式(公式写在说明和常见问题中),适合学习和估算核对;涉及安全的工程设计请以规范和实测为准。The Titration Calculator uses standard textbook formulas (given in the description and FAQ), which is good for learning and checking estimates; for safety-critical engineering follow codes and measured values.
