Metode Biloks

Menentukan biloks dan menyetarakan jumlah atom:


S O subscript 3 to the power of 2 minus sign end exponent plus Br subscript 2 yields S O subscript 4 to the power of 2 minus sign end exponent plus 2 Br to the power of minus sign




Menyetarakan jumlah ion, hidrogen, dan oksigen:


S O subscript 3 to the power of 2 minus sign end exponent plus Br subscript 2 and H subscript 2 O yields S O subscript 4 to the power of 2 minus sign end exponent plus 2 Br to the power of minus sign and 2 H to the power of plus sign


Metode Ion Elektron


S O subscript 3 to the power of 2 minus sign end exponent plus Br subscript 2 yields S O subscript 4 to the power of 2 minus sign end exponent plus 2 Br to the power of minus sign (asam)


Reduksi:


Br subscript 2 and 2 e to the power of minus sign yields 2 Br to the power of minus sign


Oksidasi:


S O subscript 3 to the power of 2 minus sign end exponent plus H subscript 2 O yields S O subscript 4 to the power of 2 minus sign end exponent plus 2 H to the power of plus sign and 2 e to the power of minus sign


Mengeliminasi elektron hingga reaksi ionnya menjadi:


S O subscript 3 to the power of 2 minus sign end exponent plus Br subscript 2 and H subscript 2 O yields S O subscript 4 to the power of 2 minus sign end exponent plus 2 Br to the power of minus sign and 2 H to the power of plus sign


Jadi, reaksi setaranya adalah: S O subscript 3 to the power of 2 minus sign end exponent plus Br subscript 2 and H subscript 2 O yields S O subscript 4 to the power of 2 minus sign end exponent plus 2 Br to the power of minus sign and 2 H to the power of plus sign.
