What is [H+] given that the measured cell potential is -0.464 V and the anode reduction ... What half-reaction occurs at the cathode during the electrolysis of molten ... PbO2(s) + 4H+(aq) + SO42-(aq) + 2e- → PbSO4(s) + 2H2O(l); E° = 1.69 V .... For the cell Cu(s)|Cu2+||Ag+|Ag(s), the standard cell potential is 0.46 V. A cell ... hopw this helps
Really, ionization takes place. It means the acid dissociates in water. Ionization is just a fancy way of saying dissociation. Always think easy.
Definition of IONIZATION: The process describing the dissociation of an acid in water.
If it ionizes or dissociates completely in water, then it shows that hydronium is a STRONG ACID. And if it ionizes partially, that shows hydronium is a WEAK ACID.
So, the answer will be choice B. by a process called ionization

Scientists look at their data and decide if the data supports the hypothesis.If the data is exactly the same after many experiments, the hypothesis is supported.If the data does not support the hypothesis, scientist may change the hypothesis or change the experiment .
