How to cite data: With the doi generated Methodology for data collection: The data collected in the excel file are the raw data obtained directly from the equipment. Data collector(s): Maria Cerrato Alvarez Date of data collection: Since January 2023 until June 2024. Person to contact with questions: macerratoa@unex.es / mtfernandeza@uniovi.es Data entry: 11/10/2024 Software (including version #) used to prepare data set: Microsoft® Excel® for Microsoft 365 MSO (version 2407) Data processing that was performed: The data was grouped and treated as shown in the corresponding article. Summarizing, the mean and standard deviation of the measurements were calculated, and the relevant statistical treatment was carried out, to make the graphs or to obtain conclusions from the data. Variables The intensity has been measured in A, the voltage in V, the time in s, the pH is dimensionless, and the concentrations in the indicated units. File Overview There is only one file, although it contains multiple Excel tabs, each one being indicated with the data to which it corresponds.
