✓ ?? 14. Two groups of students were asked to check the concentration of ammonia in a particular brand of cleaning product because there had been complaints about that brand. The students placed a 25.0mL sample of cleaning product in a volumetric flask and made it up to 250mL using distilled water. They then performed a titration by using 25.0mL of the diluted ammonia solution in a conical flask and 0.10 moll-¹ standardised hydrochloric acid in a burette. One group used bromocresol green (pH range 4.0-5.6) as the indicator and obtained the following results: Titration Volume of acid 1st 23.2 added (mL) 2nd 22.9 3rd 22.8 4th 22.9 a) Calculate the concentration of the diluted sample. b) Calculate the concentration of ammonia in 1L of the original sample.
