Correction to Spectrophotometric Calibration of pH Electrodes in Seawater Using Purified m‑Cresol Purple Regina A. Easley and Robert H. Byrne* Environ. Sci. Technol. 2012, 46, 5018−5024; DOI: 10.1021/es300491s In the original published version of the manuscript, eq 12 is appropriate to T = 273.15 K (t = 0 °C) and S = 35. The equation appropriate to T = 298.15 K and S = 35, is given as pHT (25°C , S = 35) = 7.6479 + log
