Document Summary
Made of solute (substances) & solvent (liquid). Aqueous solution- when your substance is dissolve in water. 1 mole = 6. 03 x 10^23 molecules of a compound. 1 molar (1m) solution is 1 mole of a compound dissolve in enough water to make 1 liter. Example: 1 mole nacl na(23) + cl (35. 5) = 58. 5 g/1l water. Acid - when put into water it will releases hydrogen ions. Example: stomach acid (hcl), ph of 1. Base - when put into water it will release hydroxide ions. Both acid & bases will effect your ph levels. Ph - is a measure of hydrogen ions concentrations. 1 is acidic, 7 is neutral, and 14 is basic. Buffer - is a mixture of a weak acid with its corresponding base. Buffer will react with bases and acids, to maintain a certain ph, that is optimal for survival. Is a combinations of atoms that contributes to specific properties when they are attach to larger molecules.
