Question

Write a balanced equation describing the reduction of H2SeO4 by SO2 to produce selenium. (Use the lowest possible coefficients. Include states-of-matter under SATP conditions in your answer.)

Answer 1

`\mathbf{H_2SeO_(4(aq)) + 3SO_(2(aq)) + 2H_2O_((l) ) \to Se_((s)) + 3H_2SO_(4(aq)) }`

Step-by-step explanation:

We are to write a balanced equation from the information given above by including the states of their matter according to SATP conditions;

`\mathbf{H_2SeO_(4(aq)) + 3SO_(2(aq)) + 2H_2O_((l) ) \to Se_((s)) + 3H_2SO_(4(aq)) }`

From above;

The oxidizing agent is
`\mathbf{H_2SeO_(4(aq)) }`

The reducing agent is
`\mathbf{SO_(2(aq)) }`
