Water

Is what considered a base or acid? Or does it just depends on what the problem is?

Water can act as an acid in the presence of a base, and can act as a base in the presence of an acid.

It is amphoteric which means it can act as both.

Water is amphoteric / amphiprotic so it can be both :)

To provide a more technical and detailed answer:

Water (H2O) is able to release a proton (H+) to form hydroxide ions. Water can also accept a proton to form hydronium (H3O+). Thus, water can act as both a Bronsted acid and a Bronsted base, making it amphoteric/amphiprotic.

Pure water is neutral and is neither acidic or basic. However, depending on the question and context provided, water can act as an acid or base.

Hi! Water can be considered an acid or base, depending on the reaction. If a water molecule accepts a proton in a reaction, it is considered a base. If a water molecule donates a proton, it is considered an acid. A water molecule can be considered an acid or a base based on how protons are transferred in a reaction.

Water can act as an acid or base, it just depends. This makes sense if you think about Dr. Lavelle's discussion about how molecules do not just "choose" to be an acid or a base, and it depends on their chemical environment.

Great question, as this has important biological consequences! Water is amphoteric, meaning it can act as either an acid or a base. Whether it is an acid or a base depends on its surrounding solution so in a solution with basic compounds it will act as an acid, and vice versa.

It depends on the situation- it can act as either wherever necessary because it is made up of an acidic component (H+) and a basic component (OH-)!

Depending on whether there is an acid or base present, water can act as either an acid or a base. This is because it is amphoteric.

Water comes up in several problems because it is able to act as both an acid and a base. This depends if water, H2O, gains a H+ to form H3O+ (acid), or loses a H+ to form -OH (base).

It is an amphoteric compound, which means that it can react both as an acid and as a base. So yes, it depends on the problem.

Hi! Good question. As everyone has mentioned - water can act as both, as it is amphoteric. The definition of amphoteric as used in the textbook is: "Substances that react with both acids and bases are classified as amphoteric, from the Greek word for 'both.'" I hope this helps! Good luck with your studying and learning this week everyone!

Water can gain an H+ to form hydrogen peroxide (acting as a base), H3O+. It can donate an H+ to another substance, forming OH-, and acting as an acid.

Water is amphoteric, it has the ability to act as an acid or base. Water acts as a base when mixed with acid and vice versa, this is a very important topic in acids in bases because often most acids/bases are mixed with water to truly understand their acidity or basicity.
