Answer 1

$\fbox\pink{A}\fbox\blue{n}\fbox\purple{s}\fbox\green{w}\fbox\red{e}\fbox\orange{r}$Chlorination is the most commonly used water treatment method. ... Such water will appear clear at first, turning either rusty (iron) or blackish (manganese) and cloudy in a few minutes. The same delayed reaction can happen with corrosion, too, if the problem is nearby.
