Strong electrolytes … When some substances are dissolved in water, they undergo either a physical or a chemical change that yields ions in solution. Electrolyte, in chemistry and physics, substance that conducts electric current as a result of a dissociation into positively and negatively charged particles called ions, which migrate toward and ordinarily are discharged at the negative and positive terminals … Electrolytes are substances which, when dissolved in water, break up into cations (plus-charged ions) and anions (minus-charged ions). The system is a galvanic cell, commonly known as a battery. 5-4 ELECTRODES AND ELECTROLYTES Electrode potentials If you put strips of two different metals into an appropriate electrolyte solution you are likely to find that a potential difference appears between the two strips. The difference is in the number of ions formed when the solute is dissolved. The electrolytes undergo dissociation to furnish ions either in molten state or in aqueous solutions. Electrochemistry is the branch of physical chemistry that studies the relationship between electricity, as a measurable and quantitative phenomenon, and identifiable chemical change, with either electricity considered an outcome of a particular chemical change or vice versa.These reactions involve electric charges moving between electrodes and an electrolyte (or ionic species in a solution). There are two types of electrolyte solutions which are strong and weak electrolytes. Electrolytes are present in the human body, and the balance of the electrolytes in our bodies is essential for normal function of our cells and our organs.. Common electrolytes that are measured by doctors with blood testing include sodium, potassium, chloride, and bicarbonate. An electrolyte is a chemical compound that dissociates into ions and hence is capable of transporting electric charge - i.e. NaCl, KCl, K 2 SO 4, HCl, H 2 SO 4,NaOH, NaNO 3 etc. We say they ionize.Strong electrolytes ionize completely (100%), while weak electrolytes ionize only partially (usually on the order of 1–10%). Depending on the extent of ionization (or dissociation) in water, the electrolytes are further divided into: a) Strong electrolytes: Undergo complete ionization in water. Chemically, electrolytes are substances that become ions in solution and acquire the capacity to conduct electricity. E.g.
