    between strong and weak electrolytes. In this experiment‚ a weak electrolyte‚ phenol is used‚ and the change in enthalpy is endothermic‚ ΔH=q=25.3kJ/mol. The first part of this experiment involves the neutralization of strong electrolytes. 40 mL of 2.0 M HCL was used to neutralized 50 mL of 2.0 M NaOH. Both the solutions were mixed in the calorimeter and the temperature was recorded after 2 seconds until it reaches maximum‚ then every 10 seconds for one minutes‚ and finally every 30 seconds

    stoichiometry. We are going to be reacting sodium bicarbonate (NaHCO3) and sodium carbonate (Na2CO3) with hydrochloric acid (HCl). To start off the mass of two unknown substances (being the sodium bicarbonate and sodium carbonate) will be taken. We will need to construct balanced equations for both of the reactants with the HCl and use this to guide us to figure out how much HCl will be needed to react with each of the unknown substances. When this part is through we will then need to find the percent

    Quantitative Analysis of Soda Ash by Double-Indicator Titration ABSTRACT This experiment aims to analyze the percent composition of a substance mixture by using double indicator titration. The analyte used is the soda ash which is titrated with an HCl titrant‚ standardized by 1o Na2CO3. The indicators used are phenolphthalein for basicity and methyl orange for acidity. The two volumes of the titrant are then used to calculate percent composition of soda ash analyte. Statistical parameters such
