Question

C. Drop-wise addition of NaOH(aq) to the resulting nwxture from 1b (i.e. Fe2+(aq) + 12(aq) in BASIC conditions) • Observations after: • 5 drops • 10 drops • 15 drops • 20 drops • Reduction Half Reaction • Oxidation Half Reaction • Overall Balanced Redox Reaction cell. • Explain occurrence or non-occurrence of reaction by calculating

What is the reduction half reaction, oxidation half reaction, overall balanced redox reaction, and the occurence/non-occurebce of reaction?

Answer 1

fint tey 5, 10, 15 zo doops if not * Dropwise addition of NGOH 049) in pwise addition of NAOH 049) in mix, from Feri(49) + I2C49) in Busic medium in obsegrution after 5, 10, 15 20 doops a neure busic pH like ubrie 8 thun I, renets with NYOH to produce IT and unstubie Io- which one further convested into iodate ion Io- and I ion and dissisiate. Iz + 20H - 3 I- + 10 + H2O 310- = 21-+ 103 . This reaction is known as todo lo dimetry because of stundest I teacts with Fetzins. This type of Indimetry fitration is known as Direct fitration Reln je Fe +2 + I, - fe+3 + RI- oxidation half reaction: Reduction hult reuotiem: renation: Carnscar Fet?

overall Balanced ķedox senation Fe +2 +Ļ IZ → Fe +3 + I- summary: This type of seaction is a class of Direct Iodimetry seaction. This yeaction is Indimetry because of standard solution of I diret benet with Fetz ion. so is known as Indimetry reaction, Scanned with CamScanner
