The concentration of NO3- in a water sample was determined using ion-selective electrode. A 25.00 mL of the sample is placed in a beaker and a potential of 0.102 V is obtained. A 1.00 mL aliquot of a 200.0 mg/L standard solution of NO3- is added to this sample which gave a potential reading is 0.089 V. What is the concentration (ppm) of NO3- (FW = 62.00 g/mol) in the water sample?
