Answer:
pH=3.38
Explanation:
We are given the concentrations of the weak acid and its conjugate base so we need to use the henderson hasslebalch equation
pH=pKa + log (concentration A-/concentration of HA)
A- : conjugate base NaC3H5O3
HA: weak acid HC3H5O3
so if we plug in what we are given
pH= 3.08 + log (1M/.5M)
pH= 3.38
The N from NH3 forms a coordinate
covalent bond with the metal iron as in this case. The iron itself is at the "center" of the ligate complex ion. Since the net ionic charge is at 2+, it can be said that there is one pair of unpaired electrons for <span>[fe(nh3)6]2+.</span>
