Aim: To investigate the correlation between the concentrations a base and enthalpy change in a heat of neutralization reaction. Variables: * Independent: mass of baking soda (NaHCO3) * Dependent: temperature of the product * Control: concentration of CH3COOH (0.4mol), volume of CH3COOH (100ml), volume of water (10ml) Theory: Q = mc T and H = - Q/n The enthalpy change, H is the amount of heat released or absorbed when a chemical reaction occurs at constant pressure

Tutorial on the Use of Significant Figures HOME: http://www.chem.sc.edu/faculty/morgan | WWW.CHEM.SC.EDU | © 2004 USC BOARD OF TRUSTEES | [pic] All measurements are approximations--no measuring device can give perfect measurements without experimental uncertainty. By convention, a mass measured to 13.2 g is said to have an absolute uncertainty of 0.1 g and is said to have been measured to the nearest 0.1 g. In other words, we are somewhat uncertain about that last digit —it could be a "2";
