Chemistry Project: Acids and Bases & the pH Scale

Acids and Bases atomic number 18 two groups of chemical compounds that chiefly name opposite characteristics. They have there own queer traits, pungents taste sour, turn litmus test red bandage bases taste bitter and turn litmus blue. The frontier pH relates to measuring the tartness or alkalinity of a solution, such as vinegar, or even a damp substance alike(p) soul. The achromatic pH is 7, which is essentially water, with lower rime indicating harshity and blueer numbers indicating alkalinity. Hydronium ions (H3O+) argon formed when water molecules (H2O) bond with hydrogen ions (H+). Hydronium ions are positively charged because of their extra 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 concentration of hydroxide ions are bases. Bases have a pH rating of seven or higher. Solutions of ions conduct an electric current, equal in the way that wire does. Ions croup move near in a solution and bunk a charge. If they take fire down do carry the charge they are electrolytes. The Bronsted-Lowry placement states that an dot is a proton donor and a base a proton arrogateor. Although the paneling must still contain hydrogen, the Bronsted-Lowry theory does not require an aqueous medium. The Bronsted-Lowry definition of acids and bases also explains why a strong acid displaces a weak acid from its compounds and alike for strong and weak bases. In the Lewis theory of acid-base reactions, bases donate pairs of electrons and acids accept pairs of electrons. A Lewis acid is any substance, such as the H+ ion, that toilet 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... If you want to travel by birth a full essay, or der it on our website: OrderEssay.net
