For pH, one sig fig corresponds to one decimal place (ex: 1.5) and two sig figs correspond to two decimal places (ex: 1.53) and so on. On the test, we will likely use three sig figs as per usual so answers would look like something like 1.532

Are the sig fig rules different when applied to pH, then?
