Vernier Vernier Calcium Ion-Selective Electrode (ISE)

Description

Includes

Vernier Calcium Ion-Selective Electrode, 30mL bottle of Calcium Low Standard (10mg/L), 30mL bottle of Calcium High Standard (1000mg/L), Short-term ISE soaking bottle, User manual

Used to measure concentration of Calcium (Ca2+) in aqueous samples.

• Combination-style, non-refillable, gel-filled electrode
• Data from ISE gives good indication of hardness of water (as Ca2+)
• Used as endpoint indicator in EDTA-Ca/Mg hardwater titrations
• Compatible with LabQuest™ 2, Original LabQuest, LabQuest Mini, Go!Link™, SensorDAQ™, LabPro™, EasyLink™, TI-Nspire Lab Cradle™ interfaces
• Interfering Ions: Pb2+, Hg2+, Sr2+, Cu2+, Ni2+
• Electrode Resistance: 1 to 4MOhms
• Electrode Slope (log voltage vs. concentration): +28 mV/decade
• Minimum immersion: 1.1 in.

Ion-Selective Electrodes require good chemical technique and careful calibration to obtain accurate results; they are not recommended for middle school or elementary students.
