The scope and boundaries of inorganic chemistry were shaped by the earlier field of organic chemistry in the mid-eighteenth and later centuries. Back in these earlier days of chemistry, all chemicals not classified as organic, in other words all chemicals, including minerals and alloys , that do...

The hydroxide ion has a charge of -1. This -1 charge is on the oxygen, since it has an extra electron. What is hydroxide ion simple definition? The hydroxide ion is a chemical compound with a negative charge, containing a single hydrogen and a single oxygen. It is a strong base and ...
In chemistry and cooking, many substances dissolve in water to make it either acidic or basic/alkaline. An acidic solution has a pH less than 7 while a basic solution has a pH greater than 7. Aqueous solutions with a pH of 7 are considered neutral.1Acid-baseindicatorsare substances used t...
Bronsted-Lowry Base Chemical compounds are characterized by a number of different properties, such as molecular mass, polarity, and the shape of the molecule. Another important property associated with chemicals is the acidity or basicity of the substance. When measured on the pH scale, acids and...
Just because you mix two chemicals together, don't expect you'll always get a mixture! If a chemical reaction occurs, the identity of a reactant changes. This is not a mixture. Combining vinegar and baking soda results in a reaction to produce carbon dioxide and water. So, you don't ...
In chemistry, a base can be defined as a substance that dissociates in an aqueous solution to form Hydroxide ions (OH−). A weak base is a base that doesn’t completely dissociate into its constituent ions when dissolved in a solution. Some parts of the weak base dissociate into hydroxid...
Organic Molecules Organic molecules are composed mainly of carbon and hydrogen, sometimes in combination with other elements, such as oxygen, nitrogen and others. Use Wolfram|Alpha's large database of molecules to learn about organic chemistry, from straight-chain alkanes to large fused aromatic ...
in color when brought in contact with acids and bases. This tells us whether an acid or base is being tested, with respect to the change of color. Indicators are used in a titration to show the completion of an acid-base reaction. pH indicators can be used in a variety of ways, ...
eggs, butter and flour are used to make the cake batter. Chemical equations work the same way, they provide brief information about the amount of chemicals participating in a reaction. These equations aren't limited to showing what substance undergoes a chemical change, they also show the ...
