Thus, the Answer: In short CH3CH2NH3Cl is acidic because it is formed from a strong acid (HCl) and a weak base (CH3CH2NH2). Start studying acid or base. Methylamine (CH3NH2) is a weak base and therefore cannot fully resist the tug of water molecules on the extra proton in the CH3NH3+ ion. Further supporting data shown here says that Cs+ is a soft acid, implying that Ba2+ is either soft or borderline soft. A solution of CH3NH3Cl hydrolyzes according to the equation. 8. At the equivalence point, the moles of CH3NH2 equals the moles of HCl. An acid, Citric acid to be precise. 1) The chemical reaction for the hydrolysis is: Example #5: Pyridine (C5H5N) is a weak base and reacts with HCl as follows: What is the pH of a 0.015 M solution of the pyridinium ion (C5H5NH+)? and all calculations if to justify your answer. c.

Methylamine is a reasonably strong base as bases go (#pK_B = 3.36#); it is also a potent nucleophile. Turns out, we require 62 mL or the CH3NH2 and 31 mL of the HCl for a total volume of 93 mL. The overall salt does not donate protons, the CH3NH3+ ion does (to form H3O+) when the salt is Therefore the salt is acidic because of CH3NH3+, a Bronsted acid. Although NH3 and CH3NH2 are both bases, the base strenght differs. 1) Here's the Ka expression we are interested in: 2) It comes from this reaction, the hydrolysis of CH3NH3+: 3) The concentrations of two components of the Ka expression come from the pH: This is also the concentration of the CH3NH2. a. NaNO3 b. Ba(C2H3O2)2 c. CH3NH3Cl d. C6H5NH3CHO2 e. CoBr3 NaClO- BASIC.When a weak acid reacts with a strong base the resulting solution will be basic. CH3NH3Cl + H2O -> CH3NH2Cl + H3O. At the equivalence point, the moles of CH3NH2 equals the moles of HCl. 3 is the only one that contains salts of strong bases and weak acid, so should form basic solutions in water. Answer and Explanation: Due to the reactivity of this methylammonium cation, the solution of this salt compound will be acidic (pH below 7). Can a chemical compound be both an acid and a base? Answer (1 of 12): The salt dissolved in water shows a pH slightly acid due to the difference in basic strength of Al(OH)3 and acid strength of HNO3.
