(write clearly please.) the data for the table was found by looking at these 4 graphs: use the data table and graphs to answer the following questions: 1. Determine the approximate time for the equivalence point; that is, for the biggest jump in PH in the steep vertical region of the curve (in other words the equivalence point is found in the middle of the vertical region of the titration curve. Use the experimental results to complete Table 1: Table...

Hi, can anyone please help me with this? i have no clue how to define if a reaction is Oxidation reduction or not. Thanks a lot OXIDATION-REDUCTION Introduction Chemists refer to reactions which involve a transfer of electrons from one reactant to another as oxidation reduction reactions of just "redox" reactions. Oxidation is defined as a loss of electron and reduction as a gain of electron by a substance during a chemical reaction. The loss of electrons by one substance...
