Web30 dec. 2024 · A very weak base always forms a strong conjugate acid. As we know, HNO 3 sometimes acts as the base and sometimes as an acid. So, obviously, its conjugate acid-base pair also vary with its nature. When HNO 3 acts like acid, it will make the conjugate base. When HNO 3 acts like a base, it will make the conjugate acid. Web4 mei 2015 · For NO, NO2, and HNO2, the initial concentrations were as follows: [NO] = [NO₂] = 4.83 × 10-3 M and [HNO₂] = 0.0 M. The initial partial pressure of H₂O(g) was 15.9 torr. When equilibrium was reached, the HNO₂ concentration was 6.0 × 10-4 M. Calculate the equilibrium constant, Kc, for this reaction. Kc = i

The two simple bonds + the double bond represent 4 electron pairs. So, there are still 5 electron pairs to place. One of the O forms two single bonds, so it already has 2 pairs of electrons. It needs two more pairs to get the 8e⁻. So 4 electrons are placed arround this O. The other O forms a double bond with N.
WebAmmonia (NH3) and ammonium (NH4^+) are both weak (base and acid respectively) and conjugates of each other. Your use of the Henderson–Hasselbalch equation is redundant since we only use this equation for buffers where we have a significant amount of a weak-conjugate acid/base pair.

Let's assume that both the acid's and conjugated base's concentrations are equal to 6 M. Utilize the equation: pH = pKa + log ( [A⁻]/ [HA]) pH = 6.4 + log (6 M/6 M) pH = 6.4 + log (1) pH = 6.4 + 0 pH = 6.4 The pH of our buffer is equal to 6.4.
