What Is The pH Of Ammonia?

Are you curious to know what is the ph of ammonia? You have come to the right place as I am going to tell you everything about the ph of ammonia in a very simple explanation. Without further discussion let’s begin to know what is the ph of ammonia?

What Is The pH Of Ammonia?

Ammonia, a compound with diverse uses in household cleaning products, agriculture, and various industries, holds a unique place in the realm of chemistry due to its properties as a weak base. Understanding its impact on pH requires a deeper look into its behavior when dissolved in water. Join us as we explore the pH influence of ammonia and its derivative, ammonium hydroxide, shedding light on their roles in altering the acidity or alkalinity of solutions.

Ammonia And pH:

Ammonia (NH3) itself does not possess a pH value. In its gaseous form or when dissolved in water, it does not directly contribute to the concentration of hydrogen ions (H+) or hydroxide ions (OH-) that define the pH scale. Instead, ammonia, being a weak base, can accept protons from water molecules to form ammonium hydroxide (NH4OH).

Ammonia And Ammonium Hydroxide:

When dissolved in water, ammonia reacts with water molecules to form ammonium hydroxide (NH4OH). This process involves ammonia acting as a base, accepting a proton (H+) from a water molecule, resulting in the formation of ammonium ions (NH4+) and hydroxide ions (OH-). Ammonium hydroxide, thus formed, is responsible for altering the pH of the solution.

Alkalinity And pH Influence:

Ammonium hydroxide, being a weak base, leads to an increase in hydroxide ion concentration in the solution. The presence of hydroxide ions counteracts the concentration of hydrogen ions, shifting the pH towards the alkaline side of the pH scale. Consequently, solutions containing ammonium hydroxide tend to have a higher pH value, typically above 7, indicating alkalinity.

Importance In Household And Industrial Use:

The alkaline nature of ammonium hydroxide makes it a valuable component in various cleaning products, including glass cleaners, floor cleaners, and certain detergents. Its ability to break down grease and grime, combined with its pH-altering properties, makes it an effective agent for maintaining cleanliness in household and industrial settings.

Safety Considerations:

While ammonium hydroxide is useful, it’s essential to handle it with care due to its alkaline nature. Direct contact with concentrated solutions can cause skin irritation or burns, emphasizing the importance of proper handling and dilution when using ammonia-based products.


Ammonia, while not directly contributing to pH, demonstrates its influence through the formation of ammonium hydroxide. Understanding the chemistry behind this compound allows us to appreciate its role in altering the acidity or alkalinity of solutions, contributing to its wide-ranging applications in various industries and household settings. The alkaline properties of ammonium hydroxide underscore its significance as a versatile agent, shaping its role in cleaning, industrial processes, and the manipulation of pH in aqueous solutions.


Is Ammonia Acidic Or Basic?

Ammonia is generally basic in nature (according to the Arrhenius theory as well as the Lewis acid-base theory) but can behave as an acid only in the presence of strong organic acids that can extract a proton out of it.

Is Ammonia pH 11.5 Acid Or Base?

Ammonia is a weak base with a standard pH level of about 11.

What Happens To Ammonia At High pH?

Ammonia nitrogen includes both the ionized form (ammonium, NH4+) and the unionized form (ammonia, NH3). An increase in pH favors formation of the more toxic unionized form (NH3), while a decrease favors the ionized (NH4+) form.

What Is The pH Of Baking Soda?

Baking soda, that is, sodium bicarbonate is a commonly found substance with a pH level of 9. The pH scale ranges from -1 to 15 with lesser number indicating more acidic nature whereas higher number indicating more basicity. Sodium bicarbonate can be said to be basic in nature because of its pH value 9.
