Since ions in solution retain their charges, they move readily when an electric field is applied to such a solution. The process of separation of positively and negatively charged ions that results is called electrolysis and the ionic salts that permit it are called electrolytes . The positive ions migrate toward the negative electrode and the negative ions migrate toward the positive electrode. The depression of the freezing point of water is most easily explained by the dissociation of ionic solids into ions when dissolved 10.8. In concentrated form strong acids cause painful burns and damage many substances.
Strong acids dissociate almost completely in water solution.
Weak acids remain largely in molecular form and dissociate only slightly. Bases form solutions that have a bitter taste and a slippery or soapy feeling and turn red litmus to blue. But only about 1 in ten million molecules of pure water is in ionic form. So the pH scale is based on scientific notation.
