What is most likely the pH of a solution containing many hydroxide ions (OH-) and few hydrogen ions (H )?
A solution containing many hydroxide ions (OH-) and few hydrogen ions (H+) will likely have a pH greater than 7, indicating it is basic or alkaline. The presence of excess OH- ions increases the pH, while the low concentration of H+ ions further supports this basicity. Therefore, the pH could be significantly higher than 7, depending on the concentration of OH- ions present.
A n is a substance that either contains hydroxide ions OH- or reacts with water to form hydroxide ions?
Bronsted-Lowry's BASES are a substance that either contains hydroxide ions OH- or reacts with water to form hydroxide ions.
A substance that releases OH plus ions in solution is a?
acidic
What is a substance that produces OH ions in solution is a?
a base
What defined an acid as a substance that produces H plus ions in solution and a base as a substance that produces OH- ions in solution?
The definition you provided is known as the Arrhenius definition of acids and bases. According to this definition, an acid is a substance that donates H+ ions in solution, while a base is a substance that donates OH- ions in solution. This concept helps explain the behavior of acids and bases in aqueous solutions.
What is a substance containing molecules and ions?
Water: H2O molecules, H+ and OH- ions
Why do all substances containing OH- ions are considered as bases?
The definition of an Arrehnius base is an ionic compound that contains more OH- ions than H+ ions when dissolved in water. The Bronsted-Lowry (more general) definition of a base is any substance that readily recieves protons. OH- ions very easily recieve protons (H+) to become H2O.
What kind of ions does a base substance form in water?
A base substance forms hydroxide ions (OH-) in water. This occurs when the base substance donates OH- ions to the water molecules, increasing the concentration of hydroxide ions in the solution.
What is and acid?
Acid: A substance that can donate H+ ions. Alkali: A substance that can donate OH- ions.
What is acid and allkaline?
Acid: A substance that can donate H+ ions. Alkali: A substance that can donate OH- ions.
What either accept H plus ions from solutions or donates OH- ions to solutions?
This is the definition of a base.
A n is a substance that either contains hydroxide ions OH- or reacts with water to form hydroxide ions?
Bronsted-Lowry's BASES are a substance that either contains hydroxide ions OH- or reacts with water to form hydroxide ions.
Is it true that a substance with equal numbers of H ions and OH- ions is a basic solution?
No, a substance with equal numbers of H+ ions and OH- ions is not necessarily a basic solution. In fact, a solution with equal concentrations of H+ and OH- ions is considered neutral, with a pH of 7. Basic solutions have a higher concentration of OH- ions compared to H+ ions, resulting in a pH greater than 7.
A substance that releases OH plus ions in solution is a?
acidic
Is a substance with equal numbers of H ions of OH - ions an alkaline solution?
Yes, a substance with equal numbers of H+ ions and OH- ions is an alkaline solution because it has a pH greater than 7. The presence of equal numbers of H+ and OH- ions indicates a neutralization reaction, forming water as a product.
What kind of ions do bases produce in a substance?
Bases dissociate to produce hydroxide (OH-) ions
What is the name of a substance that produces OH- ions in a solution?
A substance that produces OH- ions in a solution is called a base. Bases are usually compounds that dissociate in solution to release hydroxide ions (OH-) which can accept protons. Examples of bases include sodium hydroxide (NaOH) and potassium hydroxide (KOH).
