Science: Vernier - Nitrate

by Vernier Software & Technology

Overview

Student uses the Nitrate Ion-Selective Probe to measure the Nitrate ions concentration in water samples. In another method, student converts nitrate ions to nitrite and use the Vernier Colorimeter to measure nitrite and calculate the nitrate levels.

Key Steps

One method using the Colorimeter makes the standard curve using one standard point and finding the linear regression equation to estimate the Nitrate Ion concentration in the water sample.
Students can also use the Colorimeter with multiple standards in making the linear regression. An example of 4 standard points is shown.
