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

Re: Water
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.

Re: Water
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.

I found a diagram which accompanies this explanation! Hopefully you find it helpful!

Re: Water
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.

Re: Water
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.

Re: Water
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.

Re: Water
Water can act as either an acid of a base depending on what the situation requires. It can donate or accept a proton, making OH- or H3O respectively. Hope this helps!

Re: Water
Hi. In the lecture, Dr. Lavelle said that water acts as an amphoteric compound meaning that it can act as either an acid or base depending on the environment.

Re: Water
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.

Re: Water
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).

Re: Water
Water is amphoteric, meaning that it can act as an acid or a base, depending on the pH of what is surrounded by.

Re: Water
Water is amphoteric, so it can act as an acid or a base. It depends on the situation, the pH of the compounds it is nearby.

Re: Water
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.

Re: Water
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!

Re: Water
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.

Re: Water
Water is amphoteric and can be either an acid or base depending on what it is around. If it acts as a base its conjugate acid is H3O. If it acts as an acid its conjugate base is OH-

Re: Water
Water is amphoteric, so it can act as both an acid and base. This means it can both accept and donate an proton.

Re: Water
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.
