Is H2O acid or base?
A substance that accepts and H+ from water is considered a base. Both NH3 and H2O are amphoteric (they have H atoms that can be donated as H+ ions and thus act as acids and lone-pair electrons that can accept an H+ and thus act as bases). Thus, either NH3 or H2O can act as an acid or a base.

What is the 2 in h20?
In the chemical formula for water (H2O), what does the number 2 mean? The number 2 indicates that there are two atoms of hydrogen in a molecule of water. There is also one atom of oxygen but the number one is omitted from a chemical formula.
What is pure oxygen?
Pure oxygen or oxygen-enriched air is used in many industrial applications. The US CGA (Compressed Gas Association) and other standard-setting bodies define oxygen-enriched mixtures or atmospheres as any mixture or atmosphere containing greater than 23% oxygen. …
Is the Valency of oxygen?
The valency of oxygen is 2, because it needs two atoms of hydrogen to form water.
Is milk an acid or base?
Milk — pasteurized, canned, or dry — is an acid-forming food. Its pH level is below neutral at about 6.7 to 6.9. This is because it contains lactic acid. Remember, though, that the exact pH level is less important than whether it’s acid-forming or alkaline-forming.
Is water acidic or base?
Pure water is neither acidic or basic; it is neutral. So how does something become acidic or basic?
