The concentration of hydronium ion in solution A is 100 times that in solution B D. The hydroxide concentrations are equal in the two solutions since pH only measures the concentration of H*. 24.The self-ionization of water is A. A unimolecular dissociation of a single water molecule to H* and OH-. B. A biomolecular reaction between two water molecules to yield H3O* and OH C. A result of hydrophobic reactions D. A termolecular reaction involving the simultaneous collision of H₂O, H+ and OH-. E. None of the above

Why do strong acids and bases conduct electricity strongly compared with weak acids and bases. Select the BEST answer choice. Strong acids and bases have ions that conduct electricity while weak acids and based do not have ions. Strong acids and bases dissociate completely into ions and so ions carry the current making them a strong conductor of electricity while weak acids and bases do not dissociate completely so do not have enough ions to carry the current. Strong acids and bases are strong and so their pH level in very low or very high due to their pH level they conduct electricity. O Weak acids and bases are weak and so their pH level is very high or very low due to their pH level they conduct electricity.
