H2SO4 also known as oil of vitriol is described as the king of chemicals because of its versatility and high reactivity. Owing to its versatility it is used extensively in industries and therefore its titre determination is a frequent process. European Pharmacopoeia describes the method for titer...

2.Titration analysis is one of the important classical analytic methods of analytical chemistry experiment.使用25mL滴定管,10mL移液管,100mL锥形瓶,将常量滴定分析小量化。 3.This paper brings up the titration analysis by the inrde indicator methad instead of the outnide indicator one.提出了用内指示剂...
Take up the residue with H2SO4 and MeOH and distill as MeBO3 into water made alkaline with Na2CO3. Add one drop rosolic acid, evaporate to a small volume, make acid with HCl and expell the CO2 by heating. Adjust the pH to approximately 7.5 with N/10 HC1 or NaOH. Add sufficient ...
Topic: Mole calculations and Titrations (Read 7755 times) 2SO 2SO4would be= 0.1×50/1000= 0.005 M comparing the mole ration i would have 0.005 moles of CH3COONa since it is a one to one mole ration
H2SO4 + CuSO4 CH3COONa + CH3COOH NaCl + NaOH Answer : c) CH3COONa + CH3 COOH Q7. In the titration of a weak acid and a strong base, which of the following is utilised as an indicator? Methyl orange (3 to 4.6) Bromothymol blue (6 to 7.5) ...

例如用naoh标准滴定溶液可直接滴定hcl、h2so4等试样 (2) 返滴定法:返滴定法(又称回滴法)是在待测试液中准确加入适当过量的标准溶液,待反应完全后,再用另一种标准溶液返滴剩余的第一种标准溶液,从而测定待测组分的含量。 这种滴定方式主要用于滴定反应速度较慢或反应物是固体,加入符合计量关系的标准滴定溶液后,...
Allow a minute of so to elapse, then record the final volume of the NaOH and the final volume of HCl. For precision work, volumes of less than one drop can be rinsed off the tip of the buret with D.I. water. If your solution is too pink add 2 or more mLs of HCl (until clear...
