SUMMARY
The discussion centers on the chemical reaction involving starch, commercial bleach (sodium hypochlorite, NaOCl), and halides such as potassium iodide (KI), potassium bromide (KBr), sodium chloride (NaCl), and sodium fluoride (NaF). The proposed equation is starch + NaOCl + KI → Kstarch + NaOCl + I2, highlighting the role of halides as reducing agents and bleach as an oxidizing agent. Additionally, the interaction between starch and iodine is noted, forming a blue-black complex, which is a standard test for starch presence.
