AI Thread Summary
The discussion focuses on the chemical equation involving starch, commercial bleach (NaOCl), and halides (KI, KBr, NaCl, NaF). An attempt at the equation suggests that starch reacts with NaOCl and KI to form Kstarch, NaOCl, and I2, highlighting the role of iodine in forming a blue-black complex with starch. It is noted that halides act as reducing agents while bleach serves as an oxidizing agent. The conversation emphasizes the importance of understanding these roles in the reaction. Overall, the interaction between these compounds is crucial for the starch test and their respective chemical properties.

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.

TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...
