I2 + I– I3 –. This reaction is set up in aqueous medium. We started with 1 mole of I2 and 0.5 mole of I– in 1L flask. After equilibrium is reached excess of AgNO3 gave 0.25 mole of yellow precipitate . Equilibrium constant is Share with your friends Share 9 Nitin answered this plzzzz explain why moles of I- in solution is equal toto moles of Agi in solution 2 View Full Answer Piyush answered this But there agno3 is given 1 Srishti Singh answered this 1.33 2 Akshar Chauhan answered this The answer is 1.33 0 Aditya Tanwar answered this 1.33 because if you're wondering how 0.5-x moles is the yellow precipitate, check the stoichiometry in the balanced reaction.... moles of I negative = moles of agi (yellow precipitate) 0
