With starch added the colour change is from blue/black to ... WebLook at the two titres….titration 1 = 26.50 cm3 and titration 2 = 10.45 cm3. From the magnitude of those volumes alone we can tell that titration 1 reacts with both species and titration 2 only reacts with one species. Titration 1: this is a simple redox titration. The calculation is very very easy. So let’s do it:

Web15. aug 2024 · Redox titration is a titration in which the reaction between the analyte and titrant is an oxidation/reduction reaction. Like acid-base titrations, redox titrations normally require an indicator that clearly changes colour. In the presence of large amounts of reducing agent, the colour of the indicator is characteristic of its reduced form. ... WebClass practical. Potassium manganate(VII), KMnO 4, is a deeply coloured purple crystalline solid.It is a powerful oxidising agent. In acidic solution, it undergoes a redox reaction with ethanedioate ions, C 2 O 4 2-.The MnO 4- ions are reduced to Mn 2+ and the C 2 O 4 2-ions are oxidised to CO 2.. 2MnO 4-(aq) + 16H + (aq) + 5C 2 O 4 2-(aq) → 2Mn 2+ (aq) + 8H 2 …
