Starch, commercial bleach and halides

  1. Jan 4, 2009 #1
    1. If i were asked to write the equation for starch, bleach and halides, how am i suppose to do it?



    2. starch, commercial bleach (NaOCl), halides (KI, KBr, NaCl, NaF)



    3. My attempt at this equation: starch + NaOCl + KI --> Kstarch + NaOCl + I2

    if i'm not wrong, you should consider the typical test for starch, with iodine forming a blue black complex with the starch.

    the halides are reducing agents. and the bleach is an oxidising agent.
