Sodium hypochlorite is used in iodoform test for the oxidation of alcohol to aldehyde as shown in the image attached:
Here sodium hypochlorite is formed by the reaction of NaOH with I2 that further oxides alcohols to aldehydes.
Formula = Ca3P2
RAM of; Ca = 40 x 3 = 120g, P = 30 x 2 = 60g. 120 + 60 = 180g
Mole = 493.4g / 180g = 2.74mols
