An Experiment to determine What Factors Affect Neutralisation of 25cm³ Sodium Hydroxide Introduction Neutralisation is the reaction between an acid and an alkali that produces a neutral solution - a solution neither acidic nor alkaline. During the reaction, the acid dissociates and produces hydrogen ions, H+, and the alkali dissociates and produces hydroxide ions, OH-. If the number of H+ ions are equal to the number of OH- ions, then neutralisation occurs because there are no extra ions from either the acid or alkali to make it an acidic or alkaline solution - This neutral solution is water: H + OH = H2O. A salt is also produced, depending on what type of acid and alkali you use. The factors that affect neutralisation: - The concentration of the acid - The strength of the acid - The strength of the alkali - The temperature Preliminary Investigation We carried out a...
