For MnO 2 + K 2 CO 3 + air → Heat (B) B + C l 2 → C P i n k Which of the following is correct?
Options
- A(B)   is   green,   K 2 MnO 4   and   (C)   is   pink, Ȁ
- B(B)   is   blue,   K 2 MnO 4   and   (C)   is   pink,  
- C(B)   is   Mn 3 O 4   and   (C)   is   pink   K 2 MnO 4
- D(B)   is   Mn 2 O 3   and   (C)   is   pink   KMnO 4
Correct answer
A. (B)   is   green,   K 2 MnO 4   and   (C)   is   pink, Ȁ
Step-by-step solution
MnO 2   +   K 2 CO 3   +   1 2 O 2 → K 2 MnO 4 Green B   +   CO 2 K 2 M n O 4 + C l 2 → K M n O 4 P i n k + K C l
