    • The pH scale is logarithmic, meaning that each whole number change represents a tenfold increase or decrease.
    • A solution with a pH of 7 is neutral because it contains equal amounts of hydrogen (H+) and hydroxide (OH-) ions.
    • Acids have more H+ than OH- ions, resulting in a lower pH value.
    • Bases have fewer H+ than OH- ions, leading to a higher pH value.
    • Bases have more OH- than H+ ions, leading to a higher pH value.
    • Strong acids completely dissociate into their component ions when they are dissolved in water, while weak acids only partially ionize.
    • Weak bases do not fully dissociate into their component ions upon dissolution in water.
    • Neutral substances contain an equal amount of H+ and OH- ions, resulting in a pH of 7.
    • Weak acids only partially dissociate into their component ions when they are dissolved in water.
    • Strong acids completely dissociate into their component ions when they are dissolved in water.
    • Strong acids completely dissociate into their component ions when they are dissolved in water, while weak acids only partially ionize.
    • Solutions containing weak acids can be made stronger by adding an acid catalyst such as sulfuric acid.
    • The pH scale measures the acidity or alkalinity of a substance on a logarithmic scale from 0 to 14.
    • Neutralization reactions occur between an acid and a base, producing salt and water as products.
    • Weak bases do not fully dissociate into their component ions when dissolved in water.
    • Salt formation occurs during the reaction between an acid and a metal oxide/hydroxide.
    • The pH scale ranges from 0 (very acidic) to 14 (very basic).
    • A solution with a pH less than 7 is considered acidic, while one greater than 7 is alkaline or basic.
    • A pH of 7 indicates that there is an equal number of hydrogen (H+) and hydroxide (OH-) ions present in the solution.
    • branch of science that deals with the identification of the substances of which matter is composed; the investigation of their properties and the ways in which they interact, combine, and change; and the use of these processes to form new substances.
    • the branch of chemistry concerned with the composition, structure, properties, and reactions of atoms and molecules
    • a compound containing only carbon and hydrogen
    • a substance formed by chemical combination of two or more elements
    • a substance made up of two or more elements chemically combined in fixed proportions
    • an organic substance made up of two or more monomers joined together by covalent bonds
    • a compound containing carbon and hydrogen only
    • a compound formed by the chemical combination of two nonmetals
    • a polymer formed when many small molecules called monomers join together
    • an element consisting of pure metal
    • a type of chemical bond where electrons are shared between atoms
    • a mixture of solid particles suspended in water
    • a nonmetallic element that exists as a gas at room temperature
    • a substance consisting entirely of one element
    • a substance consisting of two or more different elements chemically united in definite proportion
    • a substance consisting of one kind of atom (or ion) only
    • the process by which an atom gains or loses electrons to form ions
    • the process of adding or removing an electron from an atom to form a charged particle
    • a substance made up of one or more elements joined chemically
    • a mixture that cannot be separated into its components using physical methods alone
    • the process that occurs when an ionic substance dissolves to form positive and negative ions in solution
