What is the pH of an aqueous solution of ammonia?

11.5
The pH of aqueous solution of ammonia is 11.5 .

Is aqueous ammonia acidic?

In aqueous solution, ammonia acts as a base, acquiring hydrogen ions from H2O to yield ammonium and hydroxide ions. In contrast, the ammonium ion acts as a weak acid in aqueous solution because it dissociates to form hydrogen ion and ammonia.

Is aqueous ammonia an acid or a base?

For this reason, ammonia is considered basic because its nitrogen atom has an electron pair that readily accepts a proton. However, ammonia is classified as a weak base which is a chemical compound that doesn’t completely break apart into ions in an aqueous solution.

What is the pH of ammonia?

11-13
Ammonia: pH 11-13.

How does ammonia affect the pH water?

While the processes that create ammonia affect pH, the aquarium’s pH can also influence the ammonia . In an acidic aquarium, ammonia actually becomes less toxic to fish. It is never good to have ammonia in an aquarium, but it is “less bad” in an acidic situation. However, some species of fish prefer water with a high pH.

Does ammonia raise pH?

The pH of Ammonia. Pure ammonia actually has a basic or alkaline pH. So in theory, ammonia should raise the pH of an aquarium. However, virtually all processes in the aquarium that produce ammonia, as well as the breakdown of ammonia produce hydrogen cations.

Does pH cause the ammonia in an aquarium to be high?

High water pH can also cause a high ammonia level in your aquarium. So, in this case, lowering the pH of the water can solve the issue. Usually, when you use coral sand or crushed coral substrate, it produces calcium that causes high PH in the water of the aquarium. Not cycling the aquarium

How does ammonia act with water?

When dissolved in water, ammonia acquires hydrogen ions from the water to produce hydroxide and ammonium ions. It is the production of these hydroxide ions that imparts ammonia’s characteristic basicity. However, not all dissolved ammonia reacts with water to yield ammonium ions, which is what makes ammonia a weak base.
