Sig Figs in pH and OH

Postby 005199750 » Fri Dec 07, 2018 11:16 pm

For pH and OH, Why is it that only the digits after the decimal point count as sig figs? Why does it have this special rule?

The number to the left of the decimal point does not affect significant figures. This is important for the log calculation.
