Which Is NOT an Error Associated with PH Measurement That

question 8

Multiple Choice

Which is NOT an error associated with pH measurement that is incorrectly defined?

• A)junction potential drift - AgCl or Ag precipitates from solution due to dilution of the KCl or the presence of reducing agents
• B)sodium error - electrode responds to Na⁺ instead of H⁺ when [Na⁺] is low and [H⁺] is high
• C)acid error - the measured pH is higher than the actual pH because the glass is saturated with H⁺ and cannot be further protonated
• D)temperature - pH meter calibrated at a different temperature than the sample
• E)equilibration time - the electrode did not have sufficient time to equilibrate with the solution
