Hello i need with this exercise in advance
the colorless thiosulphate ions in aqueous solution constitute the reducing agent of the pair s4o6 ²- / s2o3²- in a beaker a volume v1 = 10ml of an aqueous solution of orange diode i2 of molar concentration of solute c1 = 2.0 * 10 is mixed. -² mol. l-1 with a solution of sodium thiosulfate (2na + + s2o3²-) molar concentration of solute brought c2 = 5.0 * 10-² mol. l-1
1. write the equation of the reaction taking place
2. it can be seen that, starting from a certain volume v2 of added thiosulphate ions, the mixture becomes colorless
establish a progress chart of the chemical system
for a poured volume of thiosulphate ions less than v2 what is the color of the mixture?
determine the v2 volume of thiosulfate ions needed for the mixture to become colorless
how does the final composition of the system evolve when the added thiosulfate ion volume exceeds the v2 value?

Consider a uniformly charged ring in the xy plane, centered at the origin. the ring has radius a and positive charge qdistributed evenly along its circumference. a)what is the direction of the electric field at any point on the z axis? . b)what is the magnitude of the electric field along the positive z axis? use k in your answer, where k=14πϵ0. d)the ball will oscillate along the z axis between z=d and z=−d in simple harmonic motion. what will be the angular frequency ω of these oscillations? use the approximation d≪a to simplify your calculation; that is, assume that d2+a2≈a2. express your answer in terms of given charges, dimensions, and constants
