  2. Iron(II) sulfate - Wikipedia

    en.wikipedia.org/wiki/Iron(II)_sulfate

    All the iron(II) sulfates dissolve in water to give the same aquo complex [Fe(H 2 O) 6] 2+, which has octahedral molecular geometry and is paramagnetic. The name copperas dates from times when the copper(II) sulfate was known as blue copperas, and perhaps in analogy, iron(II) and zinc sulfate were known respectively as green and white copperas ...

    Globally, over 2 billion people drink feces-contaminated water, which poses the greatest threat to drinking water safety. [65] Contaminated drinking water could transmit diseases like cholera, dysentery, typhoid, diarrhea and polio. [65] Harmful chemicals in drinking water can negatively affect health. Unsafe water management practices can ...

  4. Coagulation (water treatment) - Wikipedia

    en.wikipedia.org/wiki/Coagulation_(water_treatment)

    Coagulation-flocculation process in a water treatment system. In water treatment, coagulation and flocculation involve the addition of compounds that promote the clumping of fine floc into larger floc so that they can be more easily separated from the water. Coagulation is a chemical process that involves neutralization of charge whereas ...

  5. Environmental hazard - Wikipedia

    en.wikipedia.org/wiki/Environmental_hazard

    Toxicity or other hazards do not imply an environmental hazard, because elimination by sunlight , water or organisms (biological elimination) neutralizes many reactive or poisonous substances. Persistence towards these elimination mechanisms combined with toxicity gives the substance the ability to do damage in the long term.
