In which of the following is the named atom in the $+ 6$ oxidation state? ( $H X_{2} SO X_{5}$ contains one peroxo link, so two of its O atoms are $- 1$ and the other three are $- 2$ ; in $Na X_{2} S X_{2} O X_{3}$ use the average over both S atoms.)

K X_{2} CrO X_{4}

2 + x - 8 = 0

gives Cr

+ 6

K X_{2} MnO X_{4}

: Mn

+ 6

H X_{2} SO X_{5}

2 + x + 2 (- 1) + 3 (- 2) = 0

gives S

+ 6

Na X_{2} S X_{2} O X_{3}

2 + 2 x - 6 = 0

gives an average of S

+ 2
