The attraction between a hydrogen atom on one water molecule and

the oxygen atom on another

Hydrogen bond

solvent

• The substance in which a solute dissolves

pH scale

• A measurement system to indicate the concentration of H+ ions in solution

Covalent bond

• A bond in which electrons are shared between atoms

suspension

• A mixture of water and nondissolved material; includes important biological fluids like blood

acid

• Any compound that forms H+ ions in solution

Ionic bond

• A bond formed between oppositely charged ions

cohesion

• An attraction between molecules of the same substance

mixture

• A material composed of two or more elements or compounds that are physically mixed together but not chemically combined

adhesion

• An attraction between molecules of different substances

solution

• The components (parts) of these are evenly distributed throughout

base

• A compound that produces hydroxide (OH-) ions in solution

buffer

• Weak acids or bases that can react with strong acids or bases to prevent sharp, sudden changes in pH (keep pH balanced)

solute

• The substance in a solution that is dissolved
