In high school, I was taught to add a sig fig when you take the -log to calculate the pH; however, there have been different things said about sig figs for this class regarding this topic. What is the expected rule for sig figs when taking the log that I should follow?
I posted a photo further specifying significant figures for logs. But as it states on dr Lavelles PDF of “More on Significant figures” how ever many significant figures in the number your calculating is how ever many significant figures you have after the calculation.
