Could you confirm the full name of the topic? "Natriumhydroge..." could refer to several compounds (for example, natrium hydroxide, natrium hydrogensulfate/bisulfate, natrium bicarbonate, etc.). If you specify the exact substance or provide the intended context (chemical, historical, industrial use), I can generate a concise, neutral, wiki-style article under 300 words.
