For the following reactions:

Microcosmic salt $Δ$ P ↑+ Q (solid) + $x H_{2} O$ ↑

$M n^{2 +}$ (aq) + P↑+ $H_{2} O_{2}$ $\to$ R ↓(Brown)

Q (solid) + $C o O$ $Δ o x i d i s i n g f l am e$ S (Blue coloured solid)

Answer the following questions :

Molecular weight of $S =$ $____$

Answer:

177

Solution:

$P \to NH_{3}, Q \to NaPO_{3}, R \to MnO_{2}, S \to NaCoPO_{4}$

$MnO_{2} + KOH + O_{2} Δ K_{2} MnO_{4}$
