The concentration of NO3- in a water sample is determined by a one-point standard addition using a NO3- ion-selective electrode. A 25.00-mL sample is placed in a beaker and a potential of 0.102 V is measured. A 1.00-mL aliquot of a 200.0-mg/L standard solution of NO3- is added, after which the potential is 0.089 V. Calculate the mg NO3- /L in the water sample.
