What is the relationship between a hydroxide ion and a water molecule?
A hydroxide ion is a negatively charged molecule made up of one oxygen atom and one hydrogen atom. When it combines with a water molecule, the hydroxide ion acts as a base, accepting a proton from the water molecule to form two hydroxide ions. This reaction increases the concentration of hydroxide ions in the solution.
What particle can an ammonia molecule can accept from an acid?
An ammonia molecule can accept a proton (H+) from an acid to form ammonium ion (NH4+). This reaction helps in neutralizing the acid.
A substance that does not form hydroxide ions in a water solution is a base?
This statement is not accurate. A base is defined as a substance that can accept a proton (H+) from water, forming hydroxide ions (OH-) in a solution. A substance that does not form hydroxide ions in water is not a base.
Would the alkoxide form if an hydroxide was dissolved in methanol?
No. Alkoxide ions are stronger bases than hydroxide ions. The only way of making an alkoxide is by reacting a hihgly reactive metal such as sodium with the corresponding alcohol (react sodium with methanol to produce sodium methoxide). In water sodium methoxide will react to produce sodium hydroxide and methanol.
What does pyridine act as when it reacts with water to form hydroxide?
Pyridine acts as a base when it reacts with water to form hydroxide ions. The lone pair of electrons on the nitrogen atom in pyridine can accept a proton from water, resulting in the formation of hydroxide ions (OH-) in the solution.
What molecule loses a proton to form the nitrate ion?
The molecule of nitric acid lose a hydrogen atom, not only a proton.
When a hydroxide ion accepts a proton?
When a hydroxide ion accepts a proton, it forms a water molecule. This is an example of a neutralization reaction, where an acid (donates a proton) reacts with a base (accepts a proton) to form water and a salt.
What is the relationship between a hydroxide ion and a water molecule?
A hydroxide ion is a negatively charged molecule made up of one oxygen atom and one hydrogen atom. When it combines with a water molecule, the hydroxide ion acts as a base, accepting a proton from the water molecule to form two hydroxide ions. This reaction increases the concentration of hydroxide ions in the solution.
Why a hydrogen atom can become either an ion or a part of a molecule?
Hydrogen only has one proton ,so it can pass that one proton onto another element, making it part of a molecule. It can become an ion if it loses that proton, or gains that proton.
What particle can an ammonia molecule can accept from an acid?
An ammonia molecule can accept a proton (H+) from an acid to form ammonium ion (NH4+). This reaction helps in neutralizing the acid.
Which bonds in calcium hydroxide are ionic and covalent?
In calcium hydroxide, the bond between calcium and hydroxide ions is ionic because calcium loses electrons to form a cation and hydroxide gains electrons to form an anion, resulting in electrostatic attraction. The bond within the hydroxide ion (O-H) is covalent, as the oxygen and hydrogen atoms share electrons to form a stable molecule.
A substance that does not form hydroxide ions in a water solution is a base?
This statement is not accurate. A base is defined as a substance that can accept a proton (H+) from water, forming hydroxide ions (OH-) in a solution. A substance that does not form hydroxide ions in water is not a base.
A substance that accepts a proton?
A substance that accepts a proton is called a base. Bases are typically classified as proton acceptors because they can donate a pair of electrons to form a new chemical bond with a proton. This process results in the formation of a conjugate acid.
What are the characteristics of Bronsted-Lowry base?
A Bronsted-Lowry base is a substance that accepts a proton in a chemical reaction. It can donate a pair of electrons to form a new bond with a proton. In water, Bronsted-Lowry bases can form hydroxide ions (OH-) when they accept a proton.
Is hydroxide ion basic?
Yes, hydroxide ion (OH-) is a basic ion because it can accept a proton (H+) to form water (H2O), resulting in an increase in the concentration of hydroxide ions in solution.
Is ammonia is soluble in water or a polar molecule?
Ammonia form in water ammonium hydroxide - NH4OH.
How is it possible for calcium hydroxide to have both covalent and ionic bonding?
Calcium hydroxide has ionic bonding between calcium and hydroxide ions, as calcium donates electrons to hydroxide to form ionic bonds. The hydroxide molecule itself, however, has covalent bonding between the oxygen and hydrogen atoms within the molecule.
