Soil is a chemical solution of metals
A cutting torch can be used on any material though it was made mainly for cutting metals. The heat generated may damage other materials such as wood or plastic.
The determination of metals in a solution is realized by different methods of analytical chemistry.
Metals become cations in solution.
ammonia solution is used to make the solution alkaline. In alkaline solution ,metals give colour with hydrogen sulphide.
Hydrogen.When Hydrogen burns with oxygen (from the atmosphere or supplied directly) the heat of the flame is high and is suitable for welding and cutting metals.
