The 'ash of burning magnesium' is magnesium oxide, MgO, which is alkaline when dissolved in water. However it is only slightly soluble in water, but much better in acid.

MgO + H2O --> Mg(OH)2

MgO + 2H+ ==> Mg2+ + H2O

Is magnesium oxide an acid or alkali's?

Magnesium oxide is a basic compound, also known as an alkali. It reacts with acids to form salts and water.


What acid and alkali produces magnesium chloride?

Magnesium chloride is produced by reacting magnesium hydroxide (an alkali) with hydrochloric acid. The chemical equation for this reaction is: Mg(OH)2 + 2HCl → MgCl2 + 2H2O.


Does magnesium carbonate neutralize acid?

Yes, magnesium carbonate can neutralize acid by reacting with it to form magnesium salt and carbon dioxide. This reaction helps to reduce the acidity in a solution.


What is magnesium hydroxide base-alkali or acid?

Magnesium hydroxide is a base, also known as an alkali. It is commonly used as an antacid to neutralize excess stomach acid and provide relief from symptoms of heartburn and indigestion.


What makes magnesium an acid or alkali?

Magnesium itself is a metal and does not classify as an acid or alkali. However, when it reacts with acids, it can produce hydrogen gas and magnesium salts, indicating its reactivity with acidic substances. In the presence of water, magnesium oxide can form magnesium hydroxide, which is a weak alkaline solution. Thus, magnesium's behavior in chemical reactions determines its classification in relation to acids and alkalis, but it is not inherently one or the other.


What alkali is in milk of magnesia?

Magnesium (Mg). Milk of Magnesia is Mg(OH)2


What is the alkali in antacid?

The alkali in antacids is typically compounds like calcium carbonate, magnesium hydroxide, or aluminum hydroxide. These alkalis work by neutralizing stomach acid to provide relief from symptoms of heartburn and acid reflux.


Is milk of magnesia acidic?

No, milk of magnesia is a suspension of magnesium hydroxide in water, which is a base (alkaline) rather than an acid. It is commonly used as an antacid and laxative to neutralize stomach acid and relieve constipation.


What is the procedure to neutralizing an acid?

Add an alkali. Remember the general chemical reaction Acid + Alkali = Salt + Water. However, if the acid has been ingested by a human, then give a carbonate, because the 'raw' alkali can also do damage to a human. The chemical reaction of a carbonate is Acid + Carbonate = Salt + Water + Carbon Dioxide(burp!!!). Common carbonates are sodium bi-carbonate(baking powder). or proprietary medicnes such as 'Milk of Magnesia' Milk of magnesia is a suspension of magnesium carbonate and magnesium hydroxide. .


What is the symbol equation for acid reacting with alkali?

Example 1: Acid - Hydrochloric acid - HCl Alkali - Sodium Hydroxide - NaOH Acid + Alkali -> Salt + Water HCl + NaOH -> NaCl + H2O Example 2: Acid - Hydrochloric acid - HCl Alkali - Magnesium Hydroxide - Mg(OH)2 Acid + Alkali -> Salt + Water 2HCl + Mg(OH)2 -> MgCl2 + 2H2O
