Question

Вычислите рН ацетата аммония

Answer 1

не знаю, как у вас, но у нас, если не дана молярность, то мы считаем, что она равна 0,1моль/л

Answer 2

Calculation of Ammonium Acetate pH

To calculate the pH of ammonium acetate, we need to consider the dissociation of ammonium acetate in water. Ammonium acetate (NH4CH3COO) is a salt that dissociates into ammonium ions (NH4+) and acetate ions (CH3COO-) in an aqueous solution.

The dissociation reaction can be represented as follows:

NH4CH3COO ⇌ NH4+ + CH3COO-

The ammonium ion (NH4+) acts as a weak acid, while the acetate ion (CH3COO-) acts as a weak base. The pH of the solution will depend on the concentration of the ammonium ion and the acetate ion.

To calculate the pH, we need to consider the equilibrium constant (Ka) for the dissociation of ammonium ions. The Ka value can be determined using the pKa value, which is the negative logarithm of the Ka value.

Unfortunately, the search results provided do not contain specific information about the pKa or Ka value of ammonium acetate. Therefore, it is not possible to provide an accurate calculation of the pH of ammonium acetate based on the available information.

If you have access to the pKa or Ka value of ammonium acetate, I would be happy to assist you further in calculating the pH.
