What kind of acid will dissolve a tree stump?

Answer 1

Drill holes in it and fill them with potassium nitrate soak it in and let it stay for a few months it will rot out. If you don't want to mess with potassium nitrate get a jar of stump remover, it's potassium nitrate.

As with the above answer, drill one long hole into the top of the stump. Use a long auger bit and make it the diameter to fit a good sized funnel.

Pour kerosene (paraffin) into the funnel until its full. Check the level from time to time and top up as necessary.

Once the stump and a good part of the roots system are thoroughly saturated, ignite the stump with a blow torch. It won't go up in flames, just smoulder away until the whole thing is turned to ash.

If both of these two ideas seem a bit too long winded for you, then you need the services of a stump grinding company. Using a mechanical, abrasive system, they will grind the stump down, below ground level, in short order.

Answer 2

A strong acid such as sulfuric acid is commonly used to dissolve tree stumps. It can be poured directly onto the stump to break it down over time. However, using acids to dissolve stumps can be dangerous and may have negative environmental impacts, so it's important to consider other methods of stump removal first.
