Answer 1

Answer:

in the Ph bw 4 to 10

Explanation:

Answer 2

Explanation:

Ferric coagulants or Iron coagulants are generally available in the form of ferric sulphate and ferric chlorides.

Ferric salts are generally very corrosive. Ferric Sulphate, an oxidizing agent, acts on iron pyrites to give ferrous sulphate and sulphuric acid, as the products of Step 1 of the oxidation process.

Ferric sulphate, commercially available as Ferric Flock or Ferriclear  $(\mathrm{Fe} 2(\mathrm{SO} 4) 3.3 \mathrm{H} 2 \mathrm{O})$ and Ferric chloride $(\mathrm{FeCl} 3)$  act as a coagulant in the pH range of 3.5 – 9.0.
