They take the name of electrolytes elements whose molecules to the passage of electric current through the solution of which they are immersed decompose into even smaller particles called ions and are charged with a positive electric charge and negative.
The cations are the particles, loaded with positive electricity, they are attracted to the negative pole (cathode).There are positive ions: H+, Na+, K+, Ca++, Mg++. Anions are the particles, carriers of electricity megativa shaman in the solution to the positive or knotted. There are negative ions: Cl-, HCOB- (bicarbonate), HPO4– (phosphate), SO4– (sulphate) and the radicals organic acids such as acetic acid, pyruvic acid, and many others, and finally the same molecules protein that the pH of the blood tend to charge negatively.
