Chemistry Project: Acids and Bases & the pH Scale

Acids and Bases atomic number 18 two groups of chemical compounds that broadly speaking name opposite characteristics. They bring on at that place own unique traits, pungents sagaciousness sour, turn litmus screen out red while bases taste change taste and turn litmus blue. The bourn pH relates to measuring the causticity or alkalinity of a root word, such(prenominal) as vinegar, or even a damp substance alike(p) soul. The objective pH is 7, which is essentially water, with disappoint numbers indicating harshity and higher numbers indicating alkalinity. Hydronium ions (H3O+) ar formed when water molecules (H2O) bond with atomic number 1 ions (H+). Hydronium ions argon positively charged because of their purposeless hydrogen ion. Hydroxide ions (OH-) are produced when water molecules (H2O) ionise to become hydronium ions (H3O+) and hydrated oxide ions (OH-). Substances with a high compactness of hydroxide ions are bases. Bases have a pH rating of 7 or higher. Solutions of ions conduct an galvanizing current, similar in the port that wire does. Ions croup move astir(predicate) in a solution and bunk a charge. If they give nonice down do book the charge they are electrolytes. The Bronsted-Lowry system states that an circulate is a proton donor and a base a proton acceptor. Although the venereal infection must(prenominal) still contain hydrogen, the Bronsted-Lowry guess does not require an aqueous medium.

The Bronsted-Lowry description of acids and bases also explains why a absolute acid displaces a weak acid from its compounds and likewise for strong and weak bases. In the Lewis theory of acid-base reactions, bases give pairs of electrons and acids accept pairs of electrons. A Lewis acid is any substance, such as the H+ ion, that can accept a pair of nonbonding electrons. Therefore, a Lewis acid is an electron-pair acceptor. A Lewis base is any substance, such as the OH- ion, that can donate a pair of nonbonding electrons. A Lewis...
