I'm not very sure but I think they are: Vinegar, lemon juice, black coffee, Orange Juice, battery acid (very acidic), and urine would be an extra.
A chemist would study hydrogen, oxygen, and other basic substances.
Amphoteric oxides are metal oxides that exhibit both acidic and basic behavior depending on the pH of the solution. Examples include zinc oxide and aluminum oxide.
Obviously its acid, because its name is acid
Two pollutants found in air that can make rain water more acidic are sulfur dioxide and nitrogen oxides. These pollutants can react with water in the atmosphere to form sulfuric acid and nitric acid, which then fall to the ground in the form of acid rain.
"Why won't anyone answer?" Probably because it's not clear what the question is supposed to mean. The general term for liquids/solutions that are neither acidic nor basic is "neutral", but that's so blindingly obvious that it seems unlikely to have been what you were looking for. Many liquids are neither acidic nor basic: alkanes (well, those that are liquid instead of solid or gaseous), for example. Pure water is another. Most alcohols (phenol being a significant exception ... it's not strongly acidic, but it's acidic enough that an alternative name for it is "carbolic acid").
aspirin is an acid... aspirins chemical name is acetylsalicylic acid
A chemist would study hydrogen, oxygen, and other basic substances.
acidic, alkaline higher than 7
Amino acids are, as the name suggests, both amines (basic) and acids (acidic, of course). They fall into the category of compounds known as zwitterions: chemicals that have an acidic part and a basic part in the same molecule.
Amphoteric oxides are metal oxides that exhibit both acidic and basic behavior depending on the pH of the solution. Examples include zinc oxide and aluminum oxide.
Obviously its acid, because its name is acid
Water with a pH of 7 is considered neutral, as it has an equal balance of acidic and basic properties.
Hydrogen can be found in water and air.
Chemicals, protein, ions and water
Water is a liquid that is considered neutral with a pH of 7, making it neither acidic nor basic.
In a basic sense yes. A man forget his name tried and experiment in a petri dish when he had a few substances in it namely carbon dioxide methane gas water nitrogen gas and possibly one other no oxygen though. Oxygen is acidic. He continuously ran electricity through it and he managed to create life
Body fluids, cellular secretions, and intracellular matrix
