The reaction between chlorine and hot concentrated sodium hydroxide solution is: 6NaOH + 3Cl 2 5NaCl + NaClO 3 + 3H 2 O. The unfamiliar product this time is sodium chlorate(V) - NaClO 3. As before, check the oxidation states of everything in the equation. Once again, you will find that the only thing to have changed is the chlorine.

Abstract. Granular swimming pool chlorine (calcium hypochlorite) and brake fluid (polyethylene glycol) react violently when mixed together, producing a fierce fireball. This paper proposes a mechanism which explains the production of the flammable products of the reaction by means of a radical fragmentation of polyethylene glycol.

Here's how the chemical reactions may proceed. First, bleach (NaOCl) reacts with hydrogen from ammonia (NH 3) to form hydrochloric acid (HCl): NaOCl → NaOH + HOCl HOCl → HCl + O Bleach reacts with hydrochloric acid to produce chlorine gas, salt, and water. Ammonia reacts with chlorine to make chloramine (NH 2 Cl), which is a gas.

It should be noted that the dropping of the Eh to the values less than 1000 mV could result in the instability of the gold complex. With the addition of NaCl, the reaction of HClO acid to dissolve gold and produce chlorine occurred at higher pH. Hence, the consumption of the chlorine oxidant could occur easier and ORP drops rapidly.
