Questions With Complete Solutions
Potassium - Major Intracellular cation
Electrolytes - Ions capable of carrying an electric charge
Anions, cations - Two types of Ions
Anions - Ions that carry (-) charge and move toward the anode
Cl, HCO3, PO4 - Example of anions
Cations - Ions that carry (+) charge and move toward the cathode
Na, K, Mg, Ca - Example of cations
