The acid base titration lab report is one of the most kinds of homework college students might have in their chemistry course most of the time, several weeks is the time-frame required to conduct a solid research, note down findings, structure them into coherent data clusters and then muster an engaging, informative and conclusive project. The purpose of acid base laboratory experiment was to determine equivalance points pka points for a strong acid hcl, titrated with a strong base, naoh using a drop approach in order to determine completely accurate data. The heat of neutralisation of an acid is defined as the amount of heat evolved when one equivalent of an acid and one equivalent of a base undergo a neutralisation reaction to form water and a salt similarly the heat of neutralisation of a base is the amount of heat evolved when 1 g equivalent of the base is completely neutralised by a strong.
In an acid-base titration, the neutralization reaction between the acid and base can be four lab periods assigned for this experiment in part i you will prepare an acid (hcl) solution and a base (naoh) solution these solutions will be used for all four periods so it is important to keep these then report 000 ml 5 allow about 25 ml. Hydrochloric acid, hcl, is the strong acid used in this experiment and sodium hydroxide, naoh, is the strong base the approximate concentrations of our solutions will be 01 m, and the goal of the experiment is to. An acid-base titration is the determination of the concentration of an acid or base by exactly neutralizing the acid/base with an acid or base of known concentration this allows for quantitative analysis of theshow more content.
