Explanation (EN)
The equilibrium constant Kw = [H₃O⁺][OH⁻] = 1.0×10⁻¹⁴ at 25 °C; always valid for aqueous solutions at equilibrium.
Explanation (ZH)
平衡常数 Kw = [H₃O⁺][OH⁻],25 °C 时为 1.0×10⁻¹⁴;对平衡的水溶液恒成立。
About the IPA
The International Phonetic Alphabet is a standardized system of symbols used to represent the sounds of spoken language.
It helps linguists, language learners, and educators accurately describe pronunciation across languages.
Example: the word "hello" in British English is transcribed as /həˈləʊ/ in IPA.
