Water molecules can undergo autoionization, forming hydronium (H3O+) and hydroxide (OH-) ions. However, the concentration of these ions in pure water is very low, giving it a neutral pH of around 7. This balance between hydronium and hydroxide ions is what makes water neutral.

Why does water generally has a neutral pH even though water molecules dissociate?
Water has a neutral pH of 7 because the number of hydrogen ions (H+) produced by dissociation is equal to the number of hydroxide ions (OH-) produced, resulting in a balance of acidic and basic ions. This self-ionization of water maintains a neutral pH in pure water.
What kind of bond do hydrogen and clorine make?
Hydrogen and chlorine form a covalent bond when they combine to make hydrogen chloride (HCl). In this type of bond, electrons are shared between the two atoms to achieve a stable electron configuration.
Is matter usually charge-neutral?
Yes, matter is typically charge-neutral because it contains equal numbers of positively and negatively charged particles (protons and electrons, respectively). This balance of charges allows matter to maintain a neutral overall charge.
What is the difference between mineral acids and strong acids?
Strong acids are a subset of mineral acids. Mineral acids are acids derived from inorganic compounds, while strong acids are defined by their ability to completely dissociate in water to release H+ ions. Some mineral acids, like sulfuric acid and hydrochloric acid, are considered strong acids due to their high degree of dissociation in water.
What is an acid that does not dissociate 100 percent of its ions?
A weak acid is an acid that does not dissociate completely in water, meaning it does not release all its ions. These acids typically have equilibrium reactions where they only partially ionize in solution. Examples of weak acids include acetic acid (vinegar) and citric acid.

Is a element a molecules?
Molecules are not elements. Elements make up molecules, though.
Why can gamma rays ionise atoms even though they have no mass?
This phenomenon is known as Photo electri emission. Though radiations such as Gamma, X ray, ultraviolet and even visible light are not having massive particles, they are able to eject electrons right from the neutral atoms or molecules.
Why is it that a charged object can attract a second object even if that object is neutral?
An object can have a net charge of zero, but also have sections that are charged, as long as those charges algebraically add up to zero, for example, a charge of +1 is balanced by a charge of -1 in a different location. So a charged object can be attracted to a particular part of a neutral object. This is a common phenomenon in molecular chemistry. Water molecules attract other water molecules in this manner, because they have positive and negative poles, even though the water molecule itself is neutral.
When an atom loses electrons though an ionic bond it becomes what?
neutral
Molecules move into and out of a cell though the?
Cell Membrane
Are molecules r always in motion?
Welll . . . molecules are always in motion except when their temperature is 0 degrees, Kelvin. There are not a lot of molecules that cold, though.
What kind of bond do hydrogen and clorine make?
Hydrogen and chlorine form a covalent bond when they combine to make hydrogen chloride (HCl). In this type of bond, electrons are shared between the two atoms to achieve a stable electron configuration.
Are phospholipids charged at pH 7?
Phospholipids are typically uncharged molecules at pH 7 as they have a neutral overall charge. The phosphate group in phospholipids is usually ionized and carries a negative charge, but the overall charge of the molecule is balanced by the other components, making it neutral.
Is matter usually charge-neutral?
Yes, matter is typically charge-neutral because it contains equal numbers of positively and negatively charged particles (protons and electrons, respectively). This balance of charges allows matter to maintain a neutral overall charge.
Does meteors have water?
Generally no. Comets do though.
Are intersecting lines perpendiculer?
Generally not, though they can be.
