Question

stion:
In the analysis of carbon dioxide by ion-selective electrode methodology, it is noticed that the
instrument response time is longer for carbon dioxide than it is for pH, sodium, or potassium.
Which of the following provides the correct explanation for this longer response?
a.The increased response time is needed for the chemical reaction between carbon
dioxide and the buffer surrounding the pH electrode.
b.Electrode performance is being lost and requires replacement.
c.The increased response time is needed to allow equilibration of carbon dioxide
across the membrane.

d.both a and c​
