Which German chemist studied acids, alcohol and mineral salts and described substances that initiate chemical reactions without being consumed?

Berzelius

Louis Pasteur

Justus Freiherr von Liebig

Eilhard Mitscherlich

Catalysis is the phenomenon where a substance speeds up a chemical reaction without being consumed in the process. This German chemist is connected to that idea because his work on acids, alcohols and mineral salts led him to describe substances that can initiate or accelerate reactions while remaining unchanged themselves. That insight fits the role of a catalyst, the agent that enables reactions to proceed more readily without being consumed. In the historical context, the other figures are known for different emphases—one coined the term and studied catalytic phenomena, another explored fermentation, and another advanced organic and agricultural chemistry—so this chemist’s specific focus on catalytic action best matches the description.
