Titration Lab

The purpose of this testing ground was to commit a titration on 10.000 mL of sodium hydrated oxide ascendent with 0.10 mol/L sulfuric panelling root. In this lab we performed numerous trials to comment the shoot along of sulphuric mordant source that would neutralize 10.0 mL of sodium hydroxide radical and averaged the trials to find the bill; this selective information could then(prenominal) be used to find the concentration of the sodium hydroxide resolving through outcome stoichiometry. To do this we used a burette with the capacity of 50.00 mL with an uncertainty of 0.04 mL, a pipette of 10.000 mL with an uncertainty of 0.015 mL, a clamp stand, a titration flask(an Erlenmeyer flask) and bromothymol profane indicator. The apparatus was set up like so; 0.00mL (graduation at top) Burette contains 0.10M H2SO4(aq) 50.00mL (graduation at bottom) Erlenmeyer flask contains 10.000mL of NaOH (aq) as well as bromothymol black indicator (10.000mL was metric with a pipette) Evidence Table 1: Raw Data calm from the Titration Lab showing the sign of the zodiac and final burette readings of the titrant of 0.10M ± 0.005M H2SO4(aq) qualitative Observations Before any sulfuric acerb was added, the solution was blazonless and clear. afterwards adding three drops of brymothymol spunky indicator, the solution was right away a clear full-bodied coloring material.

In the first and fourth trial, the bromothymol sour indicator caused the solution in the Erlenmeyer flask to turn a pale yellow colour from the blue colour that the solution already was after the 10.00mL of acid was added. This indicates that the solution was right off acidic. In the second, third and fifth trial, the bromothymol blue indicator caused the solution in the Erlenmeyer flask to turn a pale green colour from the blue colour that the solution already was after the respective(prenominal) amounts of acid was added to the solution. This indicates that the solution was now neutral, or close to a pH of 7.
