Explanation: For the reaction: N H + 4 + H 2O(l) ⇌ N H 3(aq) +H 3O+ Ka = [N H 3(aq)][H 3O+] [N H + 4] Ka = x2 0.35 − x, where x = [H 3O+] = [N H 3] pH = −log10[H 3O+] may be solved exactly, once we have details of Ka. And Ka = ??? Answer link WebFeb 20, 2024 · This website claims that if you add 50 m L of 0.05 M sodium bicarbonate, and 5 m L of 0.1 M sodium hydroxide (and dilute to 100 m L ), you should create a solution with p H = 9.6. I'm struggling a bit getting this result. My attempt: The sodium bicarbonate reaction would be: N a H C O X 3 + H X 2 O H X 2 C O X 3 + O H X − + N a X +

WebHow many moles of $\ce{NH4Cl}$ must be added to $\pu{2.0 L}$ of $\pu{0.10 M}$ $\ce{NH3}$ to form a buffer with $\mathrm{pH}=9$? Assume the addition does not change the volume of the solution significantly. The solution given is as follows:
WebNH 4Cl is a strong electrolyte hence, dissociates completely, NH 4OH is a weak electrolyte. Its dissociation is further suppressed by common ion NH 4+ provided by NH 4Cl in the solution. This solution acts as a basic buffer and maintains its pH around 9.25. It is capable of resisting the change in pH on addition of small amount of acid or alkali.
