What else can I help you with?
In a living cell which compound serves primarily as a substance in which most molecules and ions are dissolved?
Water serves primarily as a solvent in living cells where most molecules and ions are dissolved. Its unique properties, such as polarity and ability to hydrogen bond, allow it to dissolve a wide variety of substances necessary for cellular processes.
Can a nonionic substance can never dissolve in water?
Yes, a non-ionic substance can dissolve in water.i.e HCl - it is known as hydrogen chloride before it is dissolved in water to form hydrochloric acid.On a more generalised note, non-ionic substances tend to dissolve in water if they are polar or have a dipole-moment.
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.
The contrast of solute and solvent?
A solute is the substance that is dissolved in a solution, while a solvent is the substance that does the dissolving. The solute is typically present in a smaller quantity compared to the solvent. For example, in a saltwater solution, salt is the solute and water is the solvent.
Substance that does the dissolving?
The substance that does the dissolving is called the solvent. It is usually a liquid in which another substance, known as the solute, is dissolved. Common solvents include water, alcohol, and acetone.
An acid is a substance that ionizes in water to form what ions?
Acids dissolve in water to release hydrogen ions.
What is another word for electrolyte?
An electrolyte is a substance that ionizes when it is dissolved in ionizing solvents such as water. Another word for electrolyte would be ions.
What release hydrogen ions and ionizes in water?
An acid.
What is a substance that ionizes completely in aqueos solutions and produces h3o?
An example of a substance that ionizes completely in aqueous solutions to produce H3O+ ions is hydrochloric acid (HCl). When dissolved in water, HCl dissociates into H+ and Cl- ions, with the H+ ions combining with water molecules to form hydronium ions (H3O+).
A substance that ionizes into ions when placed in water is what?
An electrolyte.
If a substance can be dissolved in water what is that substance said to be?
If a substance can be dissolved in water, it is said to be hydrophilic or water-soluble. This means that the substance has an affinity for water and can form a homogeneous solution when mixed with it.
What is a covalent compound that is dissolves in water?
An example of a covalent compound that dissolves in water is hydrogen chloride (HCl). When HCl is dissolved in water, it ionizes to form hydronium ions (H3O+) and chloride ions (Cl-), making it acidic.
What compounds is a non electrolyte when pure but an electrolyte when dissolved in water?
A non-electrolyte when pure, but an electrolyte when dissolved in water, is typically a compound that ionizes in solution. An example is acetic acid (CH₃COOH); in its pure form, it does not conduct electricity, but when dissolved in water, it partially ionizes into acetate ions (CH₃COO⁻) and hydrogen ions (H⁺), allowing it to conduct electricity. Other examples include certain organic acids and bases that behave similarly in aqueous solutions.
Is h2s gas acidic in nature?
Yes, hydrogen sulfide (H2S) gas is acidic in nature. When dissolved in water, it forms hydrosulfuric acid, which ionizes to release hydrogen ions, making the solution acidic.
When you place a substance in water and hydrogen ion's what does that tell you about the substance?
If a substance placed in water produces hydrogen ions, it indicates that the substance can ionize and release protons (H+ ions) in an aqueous solution. This suggests that the substance is an acid, as acids typically release H+ ions when dissolved in water.
Is HBr covalent?
No, HBr is not covalent. It is an ionic compound composed of hydrogen (H) and bromine (Br) ions. The bond between hydrogen and bromine is ionic, where hydrogen donates an electron to bromine to form a bond.
What is the substance that produces hydroxyl ions when dissolved in water is a?
The substance that produces hydroxyl ions when dissolved in water is a base. Bases are substances that release hydroxide ions (OH-) in water, which can react with hydrogen ions (H+) to form water (H2O). Examples of bases include sodium hydroxide (NaOH) and potassium hydroxide (KOH).
