WebApr 11, 2024 · The residual AC + and Cl − ions were bound to the GBs or surface terminal groups, and possibly contributed to the stabilization of the α-phase by reducing the surface energy of FAPbI 3. 4, 11 Figure 1 A shows the depth profiles of Cl − ions in the perovskite thin films coated on the substrate with and without the addition of ACCl (0.3 mol ... WebWhen you add HCl to a buffer, there are three possible outcomes: (a) The HCl protonates some, but not all, of the NH 3. You still have a buffer in that case. ... NH 4 Cl ---> 0.225 mol − 0.0750 mol = 0.150 mol Note that NaOH reacts with NH 4 Cl to form NH 3 in a 1:1:1 molar ratio. 4) We are now ready for the Henderson-Hasselbalch Equation:
