Q2W8CHEM

ACIDS AND BASES

QuestionAnswer
cation positively charged ion
anion negatively charged ion,
hydroxide ion diatomic (2 atom) anion with chemical formula OH−. It consists of an oxygen and a hydrogen atom held together by a covalent bond, and carrying a negative electrical charge
hydrogen ion represented as H+ and it is the same thing as just a proton. One definition of an acid is a chemical substance that donates hydrogen ions (protons) to another chemical substance.
Concentration the abundance of a substance divided by the total volume of a mixture; most frequently it refers to solutes in homogeneous solutions.
Acid substance that donates hydrogen ions; most fruits and vegetables are slightly acidic, have a sour taste and low pH values
Base substance that accepts hydrogen ions or increases the concentration of hydroxide ions, slippery to the touch; has hydroxide ion (OH-).
Corrosive (Corrode) to destroy or damage in a certain way; most acids are very corrosive of metals.
Neutralize make chemically neutral; when acids and bases react together they can neutralize each other and make the pH value equal to 7.
pH scale logarithmic scale that represents the acidity or basicity of a substance; the pH scale changes by a factor of ten
