Ion selective electrode

BUN: 7 to 20 mg/dL CO2 (carbon dioxide): 20 to 29 mmol/L Creatinine: 0.8 to 1.4 mg/dL Glucose: 64 to 128 mg/dL Serum chloride: 101 to 111 mmol/L Serum potassium: 3.7 to 5.2 mEq/L Serum sodium: 136 to 144 mEq/L CHEM-7 is a group of blood tests that provides information about your body's metabolism. The test is commonly called a basic metabolic panel.

Ion selective electrode Selectivity And interference

NERNST EQUATION Measure E to determine 1 unknown concentration (…..so fix the other concentrations)

Reference electrodes

E + = V - E - = V E o = V

Electrolysis

If a current of 0.17 A flows for 16 min through the cell how many grams of Cu(s) will be deposited? Half that number of moles Converted to grams of Cu  g

Electrolysis

Voltametry MAYBE LATER…..
