Amphoteric Substance is one that can react as either an acid or base.
"Partly one and partly the other; neither acid nor alkaline; neutral" (I don't think this answer is correct)
The word is derived from the Greek prefix ampho- meaning "both".
Many metals (such as zinc, tin, lead, aluminium, and beryllium) and most metalloids have amphoteric oxides. Other examples include amino acids and proteins, which have amine and carboxylic acid groups, and self-ionizable compounds such as water and ammonia.
An amphoteric oxide is one which reacts with both acids and bases. An example is zinc oxide:
zinc oxide + hydrochloric acid --> zinc chloride + water
zinc oxide + sodium hydroxide --> sodium zincate + water
If a chemical is amphoteric,it means it can act both as acids and base
An amphoteric compound is one that can act as either an acid or a base.
An amphoteric substance is amphiprotic molecule which can either donate or accept a proton. Water can donate or accept a proton
Hence, water is called being amphoteric in nature.
Able to act as both an acid and a base.
No, in order for a substance to be considered amphoteric it must be able to act as an acid and a base. Sodium sulfite will only act as a base, and thus it is not amphoteric.
No. It is only an acid.
An example would be water which can gain a proton to form the hydroxonium ion (acting as a base) or donate a proton forming the hydroxide ion (acting as an acid). An acid is a proton donor; a base is a proton acceptor.
A substance that has both acidic and basic properties is said to be an amphoteric substance.
Yes. A substance with both acidic and basic properties is called an amphoteric substance. Water, while generally regarded as neutral, is actually amphoteric. Sodium bicarbonate is also amphoteric. While it usually acts as a base, it can act as an acid under highly alkaline conditions.
Water is an amphoteric substance.

No, in order for a substance to be considered amphoteric it must be able to act as an acid and a base. Sodium sulfite will only act as a base, and thus it is not amphoteric.
Am amphoteric substance can react as a base but also as an acid.
No. It is only an acid.
Yes, water can react as an acid or a base - amphoteric.
An example would be water which can gain a proton to form the hydroxonium ion (acting as a base) or donate a proton forming the hydroxide ion (acting as an acid). An acid is a proton donor; a base is a proton acceptor.

Beryllium hydroxide - Be(OH)2 - is an amphoteric substance.
Yes. A substance with both acidic and basic properties is called an amphoteric substance. Water, while generally regarded as neutral, is actually amphoteric. Sodium bicarbonate is also amphoteric. While it usually acts as a base, it can act as an acid under highly alkaline conditions.
Amphoteric substance For example, NaHCO3 Acidic part = H+ Basic part = CO32-
zinc reacts with acids as in: Zn+H2SO4-ZnSO4+H2 zinc also reacts with bases as in: Zn+2NaOH - Na2ZnO2+H2 Therefore zinc should be amphoteric metal. But none of the sites states that zinc is amphoteric
