Identify the correct statements from the following:
(I) The formula of Calgon in \(\mathrm{Na}_6\left(\mathrm{PO}_3\right)_6\).
(II) Exhausted permutit is regenerated by aqueous \(\mathrm{KCl}\) solution.
(III) Calcium stearate is soluble in water.
(IV) In ice crystals, each oxygen is surrounded by four oxygen atoms.
- A III \& IV only
- B I \& IV only
- C I \& III only
- D II \& III only
Answer & Solution
Correct Answer
(C) I \& III only
Step-by-step Solution
Detailed explanation
Exhausted permute is is regenerated by \(10 \% \mathrm{NaCl}\) solution known as Brine water. Calcium stearate is an organic calcium salt of octadexanoate. Each oxygen atom in ice crystal is surrounded by 4 ' \(\mathrm{H}\) ' atoms.
