Water is made up primarily of neutral water molecules, H2O. However, these molecules can undergo an autoprotolysis reaction, creating hydronium (H3O+) and hydroxide (OH-) ions. Note that sometimes the hydronium ions are simply represented as H+, but this notation is not strictly correct, as free hydrogen ions do not exist in aqueous solution.
What else can I help you with?
What elements make up calcium hydrogen carbonate?
Calcium hydrogen carbonate is composed of calcium ions (Ca^2+), hydrogen carbonate ions (HCO3^-), and water molecules (H2O). When dissolved in water, calcium hydrogen carbonate dissociates to form these ions.
What does water release when it dissociates?
Because of the polarity of water which causes one or two or more substances to break apart due to the unbalance of electrons in H20, which is actually neutral.
What two elements make up the chemical structure of water?
hydrogen and oxygen are the two elements which make up water
What two elements make up molecule of water?
A molecule of water, which has the formula H2O, is made up of the elements hydrogen and oxygen.
Is a substance that can take up hydrogen ions OR release hydroxide in water a base?
Yes, a substance that can take up hydrogen ions or release hydroxide ions in water is considered a base. Bases are characterized by their ability to accept protons or release hydroxide ions, which helps in neutralizing acids.
H20 consists of what ions?
Water is made up of two hydrogen atoms and one oxygen atom. Water can exist as two separate ions: a proton (H+) and a hydroxyl ion (OH-). At neutral pH, water has an equal number of both of these ions. If the water is basic, that means there are more hydroxyl ions than protons. Conversely if the water is acidic, there are more protons that hydroxyl ions.
Is table salt made up of two ions?
Yes. It is made up of Na+ ions and Cl- ions.
How many ions are there in two moles of water?
None. A water molecule is made up of three atoms covalently bonded. Occasionally, however, a water molecule will separate into H+ ans OH- ions.
What elements make up calcium hydrogen carbonate?
Calcium hydrogen carbonate is composed of calcium ions (Ca^2+), hydrogen carbonate ions (HCO3^-), and water molecules (H2O). When dissolved in water, calcium hydrogen carbonate dissociates to form these ions.
What are particles that make up a compound called?
The particles that make up a compound are called molecules or ions. Molecules are formed when two or more atoms chemically bond together, while ions are formed when atoms gain or lose electrons to achieve a stable electronic configuration.
What does water release when it dissociates?
Because of the polarity of water which causes one or two or more substances to break apart due to the unbalance of electrons in H20, which is actually neutral.
When salts are dissolved in water they form?
Salt dissolves in water to form a solution.
What two types of water make up the hydrospere?
The fresh water and salt water.
Do ions make up nonliving things?
The answer is unknown but they can engage in reactions that leave insoluble mineral deposits. These deposits can make hard water... and i have no idea what that means
How exactly does a water softener soften my water?
When calcium and magnesium build up in our water, it tends to make the water "hard." A water softener removes the calcium and magnesium and replaces it with sodium, which reduces the waters hardness. Metal ions, such as calcium and magnesium, that build up in water can react with soaps or detergents, creating a hardening effect of the water. This limits the cleaning effect of some soaps and can create build up in pipes. A water softener sends the water through an ionic exchange, where the hardness ions are replaced by sodium ions, reducing the hardness effect.
What substances give up hydrogen ions when dissolved in water?
Acids. They dissociate in water/aqueous solutions to from hydrogen ions (and the corresponding anion).
How much is two thirds of water?
Two of every three atoms that make up water is a hydrogen atom.
