What is amphoteric substance? Give one example?

Question

Answer

Metal oxide which show both acidic and basic nature and reacts with both acid and base is called amphoteric substance.

eg- aluminium oxide, zinc oxide

Answer

Substance react with both acid and base is called Amphoteric substance

Answer

Answer :

The substances which acts like both an acid and a base are known as amphoteric substances.
Examples - Aluminum Oxide and zinc oxide

Answer

Oh its too simple yrr... !!!

in simple context we can say the substance which can react with acid as well as base to form salt and water is known as amphoteric substance...

for example.. if a compound..

x + acid ---> salt + water nd also
x + base ---> salt + water

then the compound x will an amphoteric substance !!!

copper oxides nd aluminum hydroxide are the leading example of such compound !!!

Answer

Hey mate here is your answer ____!!!

according to the' Bronsted lowry theory ' of acid and base

acid : it is a proton donors

base : it is a proton accepter

in a chemistry ,an apologetic substance is a molecule or ion that can react both as an acid and as an base ,many metal such as, zinc, tin, lead, aluminum, copper are form amphoteric oxide or hydroxides, amphoteric depends on the oxidation state of the oxide

Al2O3 is an example of amphoteric oxide

the prefix of the word amphoteric is derived from the Greek word 'amphi' which means both

according to chemistry an amphoteric oxide is that which act as acids and bases both

some of the common example are as follows :-

act as base

HCL3- + H3O+ = H2CO3 + H2O

act as acid

HCL3– + CO3²– + H2O
thus it can freely accept or donate proton

thsnx

hope enough to understand

Answer

Substance which react with both acid and base...example ..aluminium oxide and zinc oxide

Answer

Amphoteric Substance:

An amphoteric substance is a chemical compound or species that can act as both an acid and a base, depending on the reaction it is involved in. These substances can accept or donate protons (H+ ions) depending on the pH of the surrounding environment. They can react with both acidic and basic substances, displaying characteristics of both acids and bases.

Example of an Amphoteric Substance:

One example of an amphoteric substance is water (H2O). Water can act as both an acid and a base, depending on the reaction it undergoes.

- Water as an Acid: In some reactions, water can donate a proton. For example, when reacting with a strong base like sodium hydroxide (NaOH), water acts as an acid by donating a proton to the hydroxide ion (OH-) to form a hydronium ion (H3O+). This reaction can be represented as: H2O + OH- → H3O+ + OH-

- Water as a Base: In other reactions, water can accept a proton. For instance, when reacting with a strong acid like hydrochloric acid (HCl), water acts as a base by accepting a proton from the hydronium ion (H3O+) to form a hydronium ion and a chloride ion (Cl-). This reaction can be represented as: H2O + H3O+ → H3O+ + Cl-

Explanation:

Amphoteric substances possess properties of both acids and bases because they contain atoms or ions that can donate or accept protons. These substances generally have a lone pair of electrons that can be used to form a new bond by accepting a proton or donating an electron pair to another species.

When an amphoteric substance reacts with an acid, it acts as a base and accepts a proton. On the other hand, when it reacts with a base, it acts as an acid and donates a proton. The ability of an amphoteric substance to act as an acid or a base depends on the nature of the other substance involved in the reaction.

Amphoterism is commonly observed in metal oxides, such as aluminum oxide (Al2O3) and zinc oxide (ZnO), which can react with both acids and bases. These oxides can react with acids to form salts and water, and with bases to form complex ions or salts.

In summary, an amphoteric substance is one that can act as both an acid and a base, depending on the reaction it undergoes. Water is a prime example as it can donate or accept protons in different chemical reactions. Understanding amphoteric substances is crucial in various fields, including chemistry, biochemistry, and environmental science.
