Equation for Chlorine with water
Cl2 + H2O ⇌ HCl +HClO
What type of reaction is the chlorine reaction with water
disproportional
why is chlorate (ClO) used for tap water
Toxic enough to kill bacteria but kept at harmless reaction
99% of water supply is wasted e.g flushing so saves lives
Equation of reaction of water in the Prescence of bright sunlight
2Cl2 + 2H2O → 4HCl +O2
Why do swimming pools exposed to sunlight need to be topped up frequently
No HClO is formed in presence of sunlight so cannot kill bacteria
What other household item contains ClO and why
Bleach -CL oxidizing agent so can remove stains as well as killing bacteria
Production of Bleach equation and necessary requirements
Cl2 + NaOH → NaClO + NaCl +H2O
cold and dilute NaOH
