In chemistry, there are two types of compounds. There are organic and inorganic compounds. They are chemical compounds. Both natural and inorganic compounds come from elements found on the periodic table. They are combinations of them to make up the organic or inorganic compound.
However, there are differences between these two different types of compounds. Organic compounds contain carbon, and inorganic compounds do not contain carbon. There are usually organisms that are found in organic compounds, and there are no organisms found in inorganic compounds.
Organic compounds include other elements on the periodic table, whereas inorganic compounds most likely do not contain other elements on the periodic table. If you want a mixture that is soluble in water, then you should go with the inorganic compounds.
