  Welcome to the Epitome of Chemistry.  Your premiere blog for all things Chemistry related. Today we will be focusing on Acid-Base Neutralization. But firstly, we must define the terms acids, bases and neutralization.   An acid is a proton donor. Acids are substances that contain H+ ions when dissolved in water. Bases are proton acceptors. They contain OH- ions when dissolved in water. When an acid and a base react, they form salt and water. The type of reaction is a neutralization reaction.  Characteristics of Acids: taste sour when they are eaten can sting the skin when they are touched can corrode (or eat away at) metals and skin can be used as a reactant during electrolysis due to the presence of mobile ions turn blue litmus paper red are studied in chemistry and biology turn red or orange on universal indicator Characteristics of Bases (Alkalis): Bitter taste (opposed to sour taste of acids) Slimy, or soapy feel on fingers Many bases react with acids and precipitate salts.
