    many different factors. This gives rise to the concept of percent yield. Sodium bicarbonate and hydrochloric acid was used in the experiment. The yields of sodium chloride reaction were determined and then compare it to the theoretical yield. HCl(aq) + NaHCO3(s) -> NaCl(aq) + CO2(g) + H2O(I) Materials and Methods In order to determine the percent yield of a reaction they will have to perform a series of instructions leading the students to the completion of the experiment.

We then proceed to separate the aspirin. We measured 30mL of NaHCO3 and mixed it with 7mL of 6M HCl. We drained the organic layer into a pre-weighed Erlenmeyer flask and save it for recovery of acetanilide. We took the combined aqueous extracts in an

    sodium carbonate‚ soda ash‚ a titration is done using a standardized solution of HCl. Aqueous HCl is a strong acid and therefore almost completely disassociates into H+ and CL-. Therefore‚ when HCl is used in a titration‚ the H+ is the titrant. Carbonate in aqueous solution is able to accept a proton‚ i.e. it acts as a base. When carbonate accepts the H+ a bicarbonate ion is formed. Na2CO3(aq) + HCl(aq)  NaHCO3(aq) + NaCl(aq) This is not the complete reaction for the titration because
