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

CHEMISTRY in Biology. Composition of Matter Matter - Everything in universe is composed of matter Matter is anything that occupies space or has mass Mass.
Water: The Facts Water is possibly the most important compound in living organisms. Water consists of 1 atom of oxygen combined with 2 atoms of hydrogen.
Acids, Bases, and pH. Acids and Bases Acids produce H + ions which react with water to form hydronium (H 3 O + ) ions Bases produce OH - ions.
