HCl is a strong acid and NaOH is a strong base. Therefore, titrating one against the other yields a complete reaction. The titration is complete when the pH reaches 7.0. Methyl orange would not be appropriate here, as the color change occurs at between 3.1 and 4.4 in an aqueous solution....

Why does the titration of a strong acid (HCl) and a strong base (NaOH) have two equivalence points, while the titration of a weak acid (CH_3COOH) and a strong base (NaOH) have only one? NH_3 is a weak base (K_b, = 1.8 x 10^-5 M) and so the salt...

A 100 mL solution of 0.1 N HCl was titrated with 0.2 N NaOH solution. The titration was discontinued after adding 30 mL of NaOH solution. The titration was completed by adding 0.25 N KOH solution. The volume of KOH required for completing the titration is : ...
HCl和NaOH溶液是经常用到的酸/碱溶液,大多数由氯化氢(硫酸)和碳酸钠混合物(碳酸氢钠)组成,它们可以用来进行重要的实验和示踪。因此,正确标定HCl和NaOH溶液是实验测试中不可缺少的一个重要步骤。 Basic Principle of Titration 标定是一种用多种方法测量化学物质浓度的方法。此外,它还可以用来测定物质的物质/碱度比...

1.12 g of KHP required 34.38 mL of an approximately 0.3 m NaOH solution in an acid/base titration to reach the equivalence point. What is the exact molarity of the NaOH solution? Using a 0.1M solution of NaOH, 25 mL 0.4823 M HCl solution was requ...
No, that's not true. pKa = pH at HALF equivalence, when exactly 50% of the acid is neutralized. But it works only for weak acids, not for a strong acid like HCl. Logged Chembuddy chemical calculators - stoichiometry, pH, concentration, buffer preparation, titrations.infoPrint...
