Question #25e82

Answer 1

`2"K"_text((s]) + "H"_2"SO"_text(4(aq]) -> "K"_2"SO"_text(4(aq]) + "H"_text(2(g])`

Explanation:

Potassium metal will react with concentrated sulfuric acid to produce potassium sulfate, a salt that exists as potassium cations, `"K"^(+)`, and sulfate anions, `"SO"_4^(2-)` in solution, and hydrogen gas.

The balanced chemical equation for this reaction is

`2"K"_text((s]) + "H"_2"SO"_text(4(aq]) -> "K"_2"SO"_text(4(aq]) + "H"_text(2(g]) uarr`

This is a very strong redox reaction in which potassium is being oxidized and hydrogen is being reduced.
