What does a positive electrode potential mean

What does a positive electrode potential mean So a negative value means that the other element or compound has a greater tendency to oxidise and a positive value means that the other element or compound has a greater tendency to be reduced The voltmeter measures the potential difference between the charge on these electrodes

Is the Positive Electrode the Cathode and Negative

So is a positive electrode where Oxidation occurs to produce positive ions which make the solution positive and the negative electrode where reduction occurs and so the ions react with the electrons from the oxidation cell hence meaning that there are less positive ions in the solution as more ions are being reduced by the electrons from the oxidation cell
