Im pretty sure everything exept sound
Sulfur dioxide<span> and </span>nitrogen oxide mix <span>with the water molecules in the atmosphere to produce acidic rain </span>
Your question isn't the most clear, but I think your answer is rocks, or more specifically phosphorous rich rocks because the phosphorous will mix with the sediments on the river's/lake's ground forming phosphorous rich rocks.
That means that It'll become a phosphate mineral and later become phosphorous again when the minerals weather.
