The empirical formula of Calgon is

Options

  1. ANa 2 PO 3
  2. BNaP 2 O 3
  3. CNaPO 3
  4. DNa 3 PO 3

Correct answer

C. NaPO 3

Step-by-step solution

The formula of calgon is Na 2 [ Na 4 ( PO 3 ) 6 ] . Calgon is a trade name of a complex salt, sodium hexametaphosphate ( NaPO 3 ) 6 . It is used for softening hard water. The empirical formula of a chemical compound is the simplest whole number ratio of atoms present in a compound. So, empirical formula of calgon will be NaPO 3 .
