Removal of hydrogen from a substance generally indicates which process?
Answer and explanation
Correct answer: Oxidation
Oxidation can be described as addition of oxygen or removal of hydrogen from a substance. Therefore, when hydrogen is removed, the process is generally identified as oxidation, making option A correct. Reduction is the opposite in this classical framework: it commonly involves addition of hydrogen or removal of oxygen. Double displacement and precipitation describe particular reaction patterns, not the specific removal of hydrogen.
