Since the titration is between a strong acid and a weak base, methylorange should be suitable as the equivalence point is around pH 5. The K of the indicator should be equal to the pH at the end point. Methyl orange is that indicator
I am guessing that you mean hydrochloric acid, and the reaction is ammonia plus hydrochloric acid gives ammonium chloride; NH3 + HCl => NH4Cl
pH of ammonia is around 11-12. Hence when you put it in a universal indicator, you get purple color.
Ammonia plus hydrochloric acid produces ammonium chloride. NH3 + HCl → NH4Cl
It depends on the concentration of the ammonia solution as the universal indicator can show a huge variety of colors.
Ammonium chloride is formed when ammonia reacts with dilute hydrochloric acid.

When ammonia diffuses woth hydrochloric acid, the ammonia is less dense than the Hydrochloric acid, thus causing the ammonia to travel faster towards the hydrochloric acid. A white solid ring should form when both gases meet.

because the particles of the ammonia are lighter so theyy movee faster
Ammonium chloride is formed when ammonia reacts with dilute hydrochloric acid.
When ammonia reacts with hydrochloric acid, a neutralization reaction occurs. The ammonia, which acts as a base, reacts with the hydrochloric acid, which acts as an acid, to form ammonium chloride and water.
Formalin is used as a preservative in the titration of ammonium chloride with sodium hydroxide to prevent the loss of ammonia gas. Ammonium chloride reacts with sodium hydroxide to produce ammonia gas, which can escape into the atmosphere if not preserved. Formalin helps to stabilize and retain the ammonia gas in solution during the titration process.
Ammonia would diffuse faster than hydrochloric acid because ammonia is a lighter molecule with a lower molecular weight, allowing it to move more quickly through a medium. Hydrochloric acid is a denser molecule with a higher molecular weight, which slows down its diffusion rate.
Ammonia gas would turn universal indicator paper blue or purple depending on the concentration of ammonia present.
The KB of ammonia (NH3) can be calculated from the half-titration point by using the expression for the equilibrium constant of the reaction: KB = [NH4+][OH-]/[NH3]. At the half-titration point, half of the ammonia has been converted to ammonium (NH4+). By knowing the initial concentration of ammonia and the volume of titrant added to reach the half-titration point, you can calculate the concentration of NH4+ and OH- to determine KB.
