What is a substance that lowers H and decreases pH when it dissociates in water?
A substance that lowers hydrogen ion concentration (H⁺) and decreases pH when it dissociates in water is an acid. When an acid, such as hydrochloric acid (HCl), dissociates in water, it releases H⁺ ions, increasing the acidity of the solution and resulting in a lower pH. This process is fundamental to understanding acid-base chemistry.
A sudtance that contain hydrogen that may be replaced by a metal is a base?
A substance that contains hydrogen that can be replaced by a metal is typically a base. The hydrogen in the substance can be exchanged for a metal ion, forming a metal salt and releasing hydrogen gas in the process. This reaction is known as a displacement reaction.
What is a substance that excepts protons and forms hydroxide ions in water?
A substance that accepts protons and forms hydroxide ions in water is known as a Brønsted-Lowry base. When such a base dissolves in water, it can accept hydrogen ions (H⁺) from water molecules, resulting in the formation of hydroxide ions (OH⁻). An example of this type of base is sodium hydroxide (NaOH), which dissociates in water to produce OH⁻ ions.
What is a substance that gives up hydrogen in a chemical reaction an alkali or a base oran acid or a metal?
A substance that gives up hydrogen in a chemical reaction is typically an acid. Acids are compounds that release positively charged hydrogen ions (H+) when dissolved in water. Alkalis, bases, and metals do not necessarily give up hydrogen ions in the same way.
What is the substance that accepts or binds hydrogen ions in a solution?
A substance that accepts or binds hydrogen ions in a solution is called a base. Bases have a pH above 7 and can neutralize acids by accepting hydrogen ions to form water. Examples of bases include sodium hydroxide and ammonia.
What is a substance that releases hydroxyl ions in a water?
A substance that releases hydroxyl ions in water is a base. Bases are substances which in water, becomes slippery, has a bitter taste, changes indicator color, forms salts with acids and promotes base catalysis. Alkaline earth materials is an example of a base.
Water is considered an acid because it releases hydrogen ions?
Water has a neutral PH value of 7 and is neither acid or base (alkaline). Since water can be represented by HOH, if we try ro argue that water is ab acid because it releases hydrogen ions, we can also argue that water is a base because it releases OH ions.
What is a substance that releases hydroxyl ions when dissolved in water?
This substance is a base.
What are Arrhenius' definitions for acid and base?
Acids are substances which produce hydrogen ionsin solution.Bases are substances which produce hydroxide ionsin solution.
What kind of substance is an acid that contains hydrogen like nitric and hydrochloric acid?
an acid is any substance that releases hydrogen ions(in other words,single protons)when added to water. the widely accepted definition is simply:"any substance that can donate a protone." inversely, a base is defined as:" any substance that absorb a proton.
Is hydrogen oxide an acid or a base?
Neither, it is water a neutral substance.
Is a substance that forms hydrogen ions in water solution a base?
false
Why is a base the name of the substance that forms hydrogen ions in water?
A base is a substance that contains hydroxide ions (OH-) which can accept protons from water, resulting in the formation of hydroxide ions and free hydrogen ions (H+). This is why a base is known to form hydrogen ions in water.
A substance that combines with hydrogen ions?
A substance that combines with hydrogen ions is called a base. Bases accept protons (hydrogen ions) to form water molecules. This process is the basis of the Brønsted-Lowry definition of bases.
What releases hydroxide ions when it is added to water?
A substance that is a base on the pH scale.
What happens in an acid base reaction according to the Arrhenius definition?
In an acid-base reaction according to the Arrhenius definition, an acid is a substance that dissociates in water to produce hydrogen ions (H+), while a base is a substance that dissociates in water to produce hydroxide ions (OH-). When an acid and a base react, the hydrogen ions from the acid combine with the hydroxide ions from the base to form water. This reaction results in the formation of a salt, which is a compound composed of the positive ion from the base and the negative ion from the acid.
What substance that releases hydroxide ions into water?
A substance that releases hydroxide ions into water is a base. Examples include sodium hydroxide (NaOH) and potassium hydroxide (KOH). When these substances dissolve in water, they dissociate into ions, including hydroxide ions (OH-), which result in an alkaline solution.
