According to Anne Helmenstine, Ph.D of About: Chemistry, bases are the chemical opposite of acids. Bases react with acids to form salts and water.Know More
Bases are substances that act as the opposite of acids; if acids are proton donors, bases are proton acceptors; if acids are electron pair acceptors, then bases are electron pair donors, etcetera. A reaction between a base and an acid is called neutralization, in which two liquid solutions (one base and one acid) combine and react to create a solution of salt and water.
Properties of bases include:
Common bases include detergents, soap, lye and household ammonia.Learn more about Acids & Bases
Some common examples of acid-base indicators include blue grapes, which can change color from deep red in an acid to violet in a base; beets, which change from red to purplish when in a very basic substance; and blueberries, which turn red in strong acids. While these are common examples, many other things can be used as an acid-base indicator.Full Answer >
Some of the properties of acids are that they conduct electricity when they are dissolved in water, liberate hydrogen when they react with active metals and, when combined with a base, will produce a salt and a neutralized base. Acids also have a pH which is less than 7 in an aqueous solution, and will change the color of blue litmus paper to red. In an operational sense, acids increase the concentration of H+ ions when they are dissolved in water.Full Answer >
According to Dictionary.com, a monoacidic base is a base that when dissolved in water produces one hydroxide ion or OH-, per molecule. In other words, a monoacidic base divides itself into two main components or molecules after reacting with water. One of the molecules is always a hydroxide ion and based on the definition of a monoacidic base, only one hydroxide ion is present.Full Answer >
Caffeine is a base. It occurs naturally in the leaves, fruits or seeds of over 60 plants worldwide, including coffee beans, cacao beans, kola nuts and many tea plants. In its purified form, it is a bitter white powder with the chemical formula C8H10N4O2.Full Answer >
