Question

1.Zaznacz związki w których Mn jest na IV stopniu utlenienia ( przykłady w załączniku)
2. Oblicz stopnie utleniania w jonach (przykłady w załączniku)

Answer 1

1. MnO(OH)2 i CaMnO3
2. Kolejno:

(-2)*4 + S = -2
-8 + S = -2
S = -2 + 8
S = VI
O = -II


(-2)*4 + Mn = -1
-8 + Mn = -1
Mn = -1 + 8
Mn = VII
O = -II


{-2}*4 + P = -3
-8 + P = -3
P = -3 + 8
P = V
O = -II


(-2)*4 + Cl = -1
-8 + Cl = -1
Cl = -1 + 8
Cl = VII
O = -II


(-2)*3 + C = -2
-6 + C = -2
C = -2 + 6
C = IV
O = -II


(-2)*2 + As = -1
-4 + As = -1
As = -1 + 4
As = III
O = -II


(-2)*3 + As = -3
-6 + As = -3
As = -3 + 6
As = III
O = -II


(-2)*3 + Mn = -2
-6 + Mn = -2
Mn = -2 + 6
Mn = IV
O = -II


1*2 + (-2)*4 + P = -1
2 + (-8) + P = -1
-6 + P = -1
P = -1 + 6
P = V
H = I
O = -II


1*1 + (-2)*4 + P = -2
1 + (-8) + P = -2
-7 + P = -2
P = -2 + 7
P = V
H = I
O = -II

Wyjaśnienie:
Tlen jest w większości przypadków na -II st. utlenienia (rzadko na II i I).
Wodór na I st. utlenienia (może być na -I, ale w innych przypadkach)
