Ответ:
volume/volume percent
molarity
molality
mass/mass percent
The right answer is volume / volume percent.
You must know that all of them are valid concentration measures. Volume / volume percent is best in this case because the volumes of two liquids can be determined very easily using the simplest lab equipment.
Ответ:
The self-ionization of water is an ionization reaction in pure water or in an aqueous solution, in which a water molecule, H₂O, deprotonates to become a hydroxide ion, OH⁻. The hydrogen nucleus, H⁺, immediately protonates another water molecule to form hydronium, H₃O⁺.
