After measuring the pH of 0.20 M NaOH, the pH of 0.10 M Acetic Acid was immediately measured without washing the pH electrode. Which of the following describes the effect on the measurement of pH of CH3COOH? A. Traces of NaOH will react with CH3COOH, and will result in an increase of pH. B. Traces of NaOH will be detected as acetic acid and will result in the decrease in measured pH. C. The CH3COOH solution will be diluted with NaOH causing an increase in pH. D. There will be no effect since the pH meter is not sensitive trace amounts of acids or bases.
