Home > News & Articles > Milk of Magnesia Formula Mg(OH)2: Definition, Properties, Preparation, Formula and Applications Magnesium Hydroxide Clinical Uses
Updated on 26th July, 2023 , 8 min read
Milk of Magnesia, also known as magnesium hydroxide, is a popular over-the-counter medication used as a laxative and antacid. It has been trusted for generations as a gentle and effective solution for relieving constipation and indigestion. But have you ever wondered about the formula that makes Milk of Magnesia work its magic? In this article, we will explore the formula of Milk of Magnesia and how it works to provide relief for various gastrointestinal issues.
Milk of Magnesia, also known as magnesium hydroxide, is a common over-the-counter medication that is used as a laxative and antacid. It is a milky white liquid or a white, odourless powder that is often taken orally to relieve constipation and symptoms of indigestion, such as heartburn and acid reflux. Milk of Magnesia is known for its ability to neutralize excess stomach acid and promote bowel movements, making it a popular choice for digestive relief. It is also used in other applications, such as oral health and skincare, due to its unique properties. Milk of Magnesia is available in various forms, including liquids, tablets, and chewable tablets, and is typically used as directed by healthcare professionals or as indicated on the product label. It is important to follow the recommended dosage and usage instructions to ensure safe and effective use of Milk of Magnesia. If you have any concerns or questions about using Milk of Magnesia, it is best to consult with a healthcare professional for personalized advice.
The chemical formula for Milk of Magnesia is Mg(OH)2, which represents the composition of this alkaline liquid. Milk of Magnesia is typically prepared by combining solutions of magnesium salt with alkaline or basic water, resulting in the precipitation of solid magnesium hydroxide, or Milk of Magnesia. The chemical reaction involved in this process is:
2OH- + Mg2+ → Mg(OH)2
However, in commercial production, a different approach is used. Calcium hydroxide, also known as lime, is treated with marine water to manufacture magnesium hydroxide. It's important to note that one ton of magnesium hydroxide can be produced from 600 cubic meters of saltwater.
The reason for the precipitation of Milk of Magnesia as a solid in this reaction is that calcium hydroxide is more soluble in water compared to magnesium. This results in the formation of solid magnesium hydroxide, which is then used to produce Milk of Magnesia. The commercial production method is more efficient in obtaining high-quality magnesium hydroxide to produce Milk of Magnesia.
Milk of Magnesia can be prepared by combining solutions of magnesium salts with alkaline or basic water. This results in a chemical reaction that typically involves the precipitation of solid magnesium hydroxide, which is the main component of Milk of Magnesia. The ionic chemical reaction can be expressed as:
2OH- + Mg2+ → Mg(OH)2 [Milk of Magnesia]
However, for commercial production, the above method is not as efficient. Instead, seawater can be treated with calcium hydroxide, also known as lime, to produce magnesium hydroxide, which is used in the production of Milk of Magnesia. It is interesting to note that one ton of Milk of Magnesia can be obtained from 600 cubic meters of seawater.
The reason for the precipitation of Milk of Magnesia as a solid in this reaction is that calcium hydroxide is much more soluble in water compared to magnesium hydroxide. This leads to the formation of solid magnesium hydroxide, which is then used to produce Milk of Magnesia. The commercial production method using calcium hydroxide and seawater is more effective in obtaining high-quality magnesium hydroxide for the production of Milk of Magnesia.
Milk of Magnesia works as a laxative and antacid due to its unique chemical properties. When ingested, it reacts with the hydrochloric acid (HCl) in the stomach to form magnesium chloride (MgCl2) and water (H2O) through a process called neutralization. The chemical equation for this reaction is as follows:
Mg(OH)2 + 2HCl → MgCl2 + 2H2O
The formation of magnesium chloride and water results in the reduction of the acidity in the stomach, which helps to neutralize excess stomach acid and alleviate symptoms of heartburn and indigestion. Additionally, the increased water content in the intestines due to the reaction helps to soften the stool and promote bowel movements, making Milk of Magnesia an effective laxative for relieving constipation.

Milk of Magnesia, also known as magnesium hydroxide, possesses several properties that make it a popular choice for various applications. Here are some of the key properties of Milk of Magnesia:
Milk of Magnesia is commonly used for the following purposes:
Just like any other substance ingested by humans, Milk of Magnesia can have adverse effects. The most common side effects, which are usually harmless, may include diarrhoea, chalky aftertaste, nausea, vomiting, and stomach cramps. However, there are more serious side effects that may occur with its use. If any of the following symptoms occur, it is important to immediately stop taking Milk of Magnesia and consult a doctor:
These side effects can also arise if Milk of Magnesia is taken in higher doses than recommended or prescribed by a healthcare professional, or if it is used for extended periods of time. It is crucial to follow the recommended dosage and duration of use, and to consult a healthcare professional if any unusual or severe side effects occur.
