Acids and bases are chemical substances that react with each other and certain other elements to produce compounds like salts. Chemists have discussed the unique reaction between acids and bases significantly, here are three major theories that attempt to explain how acids and bases react.

Theory 1: The Arrhenius acid/base theory focuses on hydrogen, and how acids and bases neutralize each other to form salt and water. Acids dissociate in a solution into hydrogen ions , while bases dissociate in a solution into hydroxide ions . An acid, when introduced to water, will increase the amount of hydrogen ions present (which can be observed as hydronium ions), or decrease the amount of hydroxide ions present. Conversely, a base will either increase the amount of hydroxide ions or decrease the amount of hydronium ions when introduced to water. This is the only way to determine if a substance is an acid or base. When an acid is introduced to a base, a neutralization reaction occurs when the protons  of the acid combine with the hydroxide ions  of the base to form water and a salt byproduct.

Theory 2: The Bronsted-Lowry theory concerns the donation of hydrogen ions from acids to bases and the formation of conjugate pairs. This theory defines acids as the substance that donates a proton, and bases as the substance that accepts the proton. Because reactions can be reversible, acids that have their hydrogen ion removed become that acid’s conjugate base, while bases that receive that hydrogen ion become the original base’s conjugate acid. This is true because if the reaction is reversed, the former-acid with its missing proton will be receiving the hydrogen ion (making it the base) and the former-base with the additional proton will be donating it (making it the acid). Reactions then produce new bases and acids, and do not neutralize to produce salts and water. This acid-base theory does not require a solvent.

Theory 3: The Lewis theory discards the concern with hydrogen ions and focuses on electron-pair donation. According to this theory, acids are substances that can receive an electron pair whereas bases are substances that can donate an electron pair. This broadens the consideration of what is a base or an acid even further, eliminating the need to define substances based on their use of a hydrogen ion. Compounds that have vacancies in their electron octets can be considered Lewis acids, and compounds with extra electrons in their octets can be considered Lewis bases.

Which theory supports the concept that acid-base reactions are based on donations between acids and bases?

Suppose theory 2 is proven correct and theories 1 and 3 are debunked. What would be the result of this?

The Environmental Protection Agency compiled the following information about heavy metals in drinking water. Heavy metals are toxic, and thus must be monitored very closely. All amounts are given in parts per billion (ppb), a common measurement of concentration for trace contaminants. Figure 1 shows total heavy metal contamination in each city as a makeup of various percentages of specific contaminants. Figure 2 shows specific amounts of contaminants (with the same color coding) in ppb as well as total contamination level in ppb.
