Complete and balance the following chemical equation. Assume the reaction takes place in an acidic aqueous solution. NO3- + S2- arrow S8 + NO2

Arsenic Acid Formula- Arsenic acid is a chemical compound that has a formula H3AsO4. Descriptively, we write it as AsO(OH)3. Also, it is a colorless acid that is the arsenic analog of phosphoric acid. Besides, the phosphate and arsenate salts behave very correspondingly.

Arsenic acid(H3AsO4) is a weak triprotic acid. Write the Ka equations for the dissociation of each H+ from arsenic acid. (Be sure to indicate the relevant charges and states of each species in your equations.) Farmers who raise cotton once used arsenic acid, …
