KMnO4 react with KI in basic medium to from I2 and MnO2. When 250mL of 0.1 M KI solution is mixed with 250 mL of 0.02MKMnO4 is basic medium, What is the number of moles of I2 formed ?
+I→MnO2+I2 Number of milli equivalent of MnO4−=0.02×3×250=15 Number of milli equivalent of I−=0.1×1×250=25 ∴Number of milli equivalents of I2 formed=n− factor X number of milli moles Number of milli moles I2 from =
