Investigating a Neutralisation Reaction Between Hydrochloric Acid and Sodium Hydroxide

Investigation of Neutralization Reaction of Hydrochloric Acid and Sodium Hydroxide In order to investigate the neutralization reaction, it is necessary to know all the factors that affect it in order to investigate this. The following are all factors: Temperature - this greatly affects exothermic or endothermic reactions. When concentration - solution concentration is high, it means that it contains more reactant particles.

Objective My goal is to find the amount of hydrochloric acid required to neutralize sodium hydroxide. Theoretical titration is a laboratory method for analyzing chemical concentration. In this experiment, it is necessary to neutralize 10 cm 3 of sodium hydroxide with 10 cm 3 of hydrochloric acid. In this experiment, phenolphthalein was used as an indicator. In this case, the base was pink and the acid was white turbid. When they are used to neutralize each other, the mixture becomes transparent at the end point. The end point is the same number of moles in the two solutions.

Since sulfuric acid is an acid, it needs to be neutralized with a base. Commonly used neutralizing bases include sodium hydroxide, sodium carbonate, calcium hydroxide and the like. Sodium hydroxide, also known as caustic, is the most widely used alkaline neutralizing agent in the industry. Because of its high solubility, it is effective, inexpensive and easy to handle. In order to neutralize sulfuric acid, NaOH was slowly and cautiously added to the acid until the end point was reached. A relatively safe sodium sulfate aqueous solution will be formed as product. The neutralized acid is then collected in plastic containers and disposed of in accordance with local regulations.

The following is an experiment of how the temperature change in the exothermic reaction occurring between sodium hydroxide (NaOH) and hydrochloric acid (HCl) and the concentration of acid change these results. The reaction is characterized by neutralization, energy change (indicated as temperature change), and usually exothermic (heat release). The neutralization reaction is exothermic since bonds are destroyed and formed during the reaction. When the bonds are destroyed, the energy in these bonds is absorbed. In that case, it is called a temperature change and the temperature rises. In the case of an endothermic reaction, the reaction is consumed more energy to destroy the bond, so the temperature drops.
