Outline the procedure of a titration experiment to determine the concentration of ammonia in the organic layer.

NB: Given 0.010 mol dm^-3 hydrochloric acid, methyl orange indicator and lab apparatus commonly used for titration.

1. Fill up a burette with 50.00cm³ of 0.010mol/dm³ HCl
2. Using a dry pipette, transfer 10.0 cm³ of the organic layer into a 250cm³ conical flask.
3. Using a measuring cylinder, add 20 cm³ of deionised water into the conical flask, then add 2-3 drops of methyl orange. 
4. Titrate the resulting mixture against 0.010mol/dm³ HCl until the colour of methyl orange changes from yellow to orange.
5. Repeat the titration until 2 consistent readings are obtained.
