The taste of lemons and lime, the bite of sourdough bread, and the tang of a tomato are all caused by acids. Acids may be defined as substances that produce H. +. ions in solution. Citric acid, acetic acid, and tartaric acid are shown here.. Some Important Acids. (All acids have H atoms). Properties of Acids. Sour Taste. Reacts with Metals (Produce Hydrogen Gas). Reacts with Carbonates (Produce CO2). Turn Litmus Paper Red. Natural Indicators. Acid and Base Notes. I can distinguish between an acid and a base..

Unit 8: Acids & Bases PART 1: Acid/Base Theory & Properties I hereby define acids as compounds of oxygen and a nonmetal. (1777) In fact, I just named the newly discovered gas oxygen , which means “acid-former.” Rola. M. . Shadid. , BDS, . MSc. The denture base supports the artificial teeth and consequently receives the functional forces from occlusion & transfers functional forces to supporting oral structures.
