This means that no HCl or NaOH molecules exist, instead everything is broken up into equivalents of H+, Na+, Cl- and OH- in solution.

#Serial dilution lab conclusion full#

In every case, with every molecule, full ion dissociation occurs. In the case of NaOH, Na+ readily gives up its 1 equivalent of OH- anion in solution and the two separate according to the reactions below:

In this experiment, the strong acid, HCl, and the strong base, NaOH, are used to create serial dilutions which are combined to form salt solutions of NaCl according to the reaction below:Д«ecause HCl has strong dissociative forces, it readily gives up its 1 equivalent of H+ cation, which floats away in solution from the Cl- anion. When an acid has lost its H+, it is now the conjugate base and, likewise, when the base has gained an H+-, it becomes the conjugate acid.ДЄcid: CH 3COOH, Conjugate Base: CH 3COO. In the case of bases, alkali metal bases (LiOH, NaOHвЂ¦) are strong, and most others are weak.ДЄcids and bases have a relationship to each other through conjugate acids and conjugate bases.

Therefore, it is helpful to group all the halogenic acids (HF, HCl, HBr, HI) and sulfuric acid (H 2SO 4)as strong acids, while most other common acids are considered weak. Acids strengths are characterized quantitatively by K a (acid/base dissociation constants) and pK a (-log K a), but in most common conversation, referring to a molecule as a strong acid or strong base means that it will 100% fully dissociate into ions when mixed into a solvent such as water. The difference between a dissociative strong or weak molecule is clear for very strong cases, but when moderate driving forces are present, the differentiation between strong and weak becomes situation conditional.

Molecules that form strong acids and bases have a much greater ability to give away H+вЂ™s or OH-вЂs compared to вЂњWEAKвЂќ acids and вЂњWEAKвЂќ bases.

The terms вЂњSTRONGвЂќ acid and вЂњSTRONGвЂќ base refer to the relevant strong driving forces that cause the dissociation of H+ (protons) or OH- (hydroxide ions), respectively. This breaking apart of the ions is called dissociation. Basically, what this means is keeping in mind how easily the molecule can break into its component ions. Concerning the concepts of acids and bases, it is important to keep in mind the relative dissociative strength of the molecules in solution.
