WebJan 30, 2024 · Nevertheless, there are hydroxide ions there, and we can squeeze this into the Arrhenius theory. However, this same reaction also happens between ammonia gas and hydrogen chloride gas. NH3 (g) + HCl (g) → NH4Cl (s) In this case, there are not any hydrogen ions or hydroxide ions in solution - because there isn't any solution. WebSo that's gonna give us the concentration of hydronium ions, H3O+, is equal to 10 to the negative 9.25. And 10 to the negative 9.25 is equal to 5.6 times 10 to the negative 10. So the concentration of hydronium ions in our solution at 25 degrees Celsius is equal to 5.6 times 10 to the negative 10th molar. horn turning
