WebDec 30, 2024 · Therefore, Ammonium hydroxide (NH 4 OH) is a base, with a pH lies between 7 to 10. NH4OH acting as Arrhenius base and Bronsted-Lowry base. The base dissociation constant value (K b) for NH 4 OH is 1.8 × 10-5 that’s way lower than recommended value for the Strong base, hence, NH 4 OH is a weak base in nature. WebBased on the molar masses of HCl and NH4OH, did you expect to see the formation of NH4CI closer to the HCI end of the tube or the NH4OH end of the tube? Explain why. 2. Why do think it was necessary to place Parafilm on the ends of the tube? 3. Was your average percent error very high (greater than 5%)?
