Alkaline minerals are elements from within the earth. They fall underneath the group 2A on the periodic table. They are reactive which means they have the tendency to react chemically to a situation rather than creating or controlling it. Electropositive is an element that loses electrons and form positive ions in chemical reactions. Elements on the left side of the periodic table are electropositive (+) and as you travel to the right side of the chart the more electronegative (-) the elements.
Atoms need to bond to become stable, this is where the term opposites attract comes in to play. Ultimately this is what creates the flow of electrical currents in the water. When earth metals bond to non metals they create a chemical bond known as a ionic bond which is an electrostatic attraction between two oppositely charged ions for the creation of salt (Na+Cl-).
When a metal oxide is dissolved in water it creates an alkaline solution. Divalent metals are atoms that are each capable of chemically combing with two atoms of hydrogen and can form basic oxides which react with water to form hydroxide. Basic oxides are properties that opposes acidic oxides by reacting with water to form a base or with an acid to form salt and water. This solution naturally creates a sodium bicarbonate that is released into the blood to neutralize acidity within the body.
This process takes place when alkaline water and alkaline foods with high water content mixes with the stomach acid. Sodium Carbonate also known as soda ash which is a base used for buffering acidity. Metals are good conductors of electricity because of the free electrons which allows the electrical currents to flow through. Salts dissolve in water making the water a conductor of electrical currents which conducts electricity for the body.
