neutralization for the reaction of sodium hydroxide (NaOH) and hydrochloric acid (HCI). Requirement The heat of neutralization (∆Hneutzn ) is the heat transferred when 1 mol of an acid reacts with 1 mol of a base. This heat is generally reported in either kilojoules per mole (kJ/mol) or kilocalories per mole (kcal mol). The reaction of HCI and NaOH solutions is shown in Equation 1. HCI(aq) + NaOH(aq) H20(l) + NaCI(aq) (Eq. 1)

divided in half with a pH substrate side tested against a control side. The movements and actions of the test slaters were recorded at constant time intervals. The results observed illustrate the preference of a basic NaOH in comparison to the acidic HCI solution. The explanation of this result can be referred against previous studies‚ which illustrate mechanisms such as conglobation and thigmokinesis employed by slaters in order to create a stable environment whilst in unfavourable conditions.
