An average day

Someone told me a long time ago that water and electricity doesn't mix?
In the 1960's my father had a project which utilized copper conductors that were pipe. Water flowed through the pipe to prevent it from melting.

Grok said:
"Pure H₂O, in its ideal form, does not conduct electricity effectively because it contains no free ions or charged particles to carry an electric current. Water molecules are neutral, with a covalent bond between hydrogen and oxygen, and pure water has a very low concentration of ions due to minimal self-ionization (H₂O ⇌ H₃O⁺ + OH⁻). This self-ionization produces an extremely small number of ions (about 10⁻⁷ M at 25°C), resulting in very high electrical resistance.However, in practice, even "pure" water may contain trace impurities, dissolved gases (like CO₂, which can form carbonic acid), or ions from containers, which can slightly increase conductivity. For significant conduction, water typically needs dissolved electrolytes, like salts, to provide free ions.So, theoretically, pure H₂O is a poor conductor, but real-world "pure" water may conduct slightly due to impurities or self-ionization."
