In aqueous solution, ammonia deprotonates a small fraction of the water to give ammonium and hydroxide according to the following equilibrium: . NH 3 + H 2 O ⇌ NH + 4 + OH −.. In a 1 M ammonia solution, about 0.42% of the ammonia is converted to ammonium, equivalent to pH = 11.63 because [NH +
The table above gives properties of the vapor–liquid equilibrium of anhydrous ammonia at various temperatures. The second column is vapor pressure in k Pa . The third column is the density of the liquid phase.

Every home cook should have a working, non-expired fire extinguisher, but many of us aren't super confident when it comes to actually using one. Fire blankets aim to make putting out small fires ...
Using rubber pumps, air (acting as gas-carrier) is injected in the gas-washing tubes causing the streams of ammonia and hydrogen chloride in air to collide and react giving the solid product, ammonium chloride. It is a product of the Solvay process used to produce sodium carbonate: [3] CO 2 + 2 NH 3 + 2 NaCl + H 2 O → 2 NH 4 Cl + Na 2 CO 3
Police in Madison, Wisc., said Monday they were investigating reports of a shooting that left multiple people injured at a Christian school. The incident occurred at Abundant Life Christian School ...
In late July, Super Micro's auditor at the time, Ernst & Young (EY), raised concerns about the company's governance, transparency and internal control over financial reporting, prompting its board ...
Buffer capacity falls to 33% of the maximum value at pH = pK a ± 1, to 10% at pH = pK a ± 1.5 and to 1% at pH = pK a ± 2. For this reason the most useful range is approximately p K a ± 1. When choosing a buffer for use at a specific pH, it should have a p K a value as close as possible to that pH.
