In this experiment‚ there are 3 parts need to be done which is complex formation‚ weak acids and bases and precipitation reaction. During complex formation experiment‚ student needs to observe the different reaction occur when adding ammonia or sodium hydroxide in small quantity and in excess. At the second part‚ student needs to measure the pH of different solution by using universal indicator paper and determine whether each solution is acidic‚ basic or neutral. Lastly‚ the precipitation reaction

Objective: To study the affect of pH on a food preservative. Chemical Equation: C6H5COONa + HCL ------ C6H5COOH + NaCl Procedure: This experiment was started with a clear solution of sodium benzoate and HCl was added to it‚ ultimately producing benzoic acid. First‚ .3395 g of sodium benzoate was weighed‚ then it was dissolved in water‚ causing it to disassociate into ions. Next‚ 3M of HCl were added drop wise to the solution until it reached a pH of 2‚ thus introducing the hydronium

concentrain of sulphuric acid Aim The point of this investigation is to find out the concentration of the sulphuric acid in my experiment. I will do this by titrating the sulphuric acid with sodium carbonate. H2SO4 + Na2CO3 à Na2SO4 + H2O + CO2 Acid + Alkali à Salt + Water + Carbon dioxide Ratio of sulphuric acid to sodium carbonate: H2SO4 : Na2CO3 1 : 1 Concentration of sulphuric acid: H2SO4 is approximately 0.05 - 0.15 moldm-3 The average concentration of the sulphuric acid is: 0.05 + 0.15 = 0
