There are general trends that one should try to keep in mind when determining acidity/basicity of compounds. Zinc oxide (ZnO) reacts with both acids and with bases: This reactivity can be used to separate different cations, such as zinc(II), which dissolves in base, from manganese(II), which does not dissolve in base. See below. Download BYJU’S – The Learning App, to explore the amazing world of Chemistry with detailed explanations and creative videos. Acidic (primarily) B. For example, the metal oxide ZnO contains no hydrogen and cannot donate a proton. Instead it is a Lewis acid whose Zn atom accepts an electron pair from the base OH−. Similarly reacts with the alkali to form salt and water, exhibiting acidic property. It is a conjugate base of … Water, amino acids, hydrogen carbonate ion (bicarbonate ion) and hydrogen sulfate ion (bisulfate ion) are common examples of amphiprotic species.

One type of amphoteric species are amphiprotic molecules, which can either donate or accept a proton (H+).

Ga2O3 7. Al2O3 3. Can you explain this answer? Classify each of the following oxides according to whether it is primarily basic, acidic, or amphoteric.

The prefix of the word 'amphoteric' is derived from a Greek prefix amphi-, which means both. Example: aluminium oxide. It has a role as a human metabolite, a Saccharomyces cerevisiae metabolite and a mouse metabolite. Hydrogensulfite is a sulfur oxoanion. [1] What exactly this can mean depends on which definitions of acids and bases are being used. , Using Standard Molar Entropies), Gibbs Free Energy Concepts and Calculations, Environment, Fossil Fuels, Alternative Fuels, Biological Examples (*DNA Structural Transitions, etc. An acidic oxide is an oxide which when combined with water gives off an acid. Amphoteric oxides are compounds of oxygen which exhibits both acidic as well as basic characteristics. 1. This discussion on Which of the following oxides are acidic, Basic Amphoteric Respectively.a)MgO, P4O10, Al2O3b)N2O3, Li2O, Al2O3c)SO3, Al2O3, Na2Od)P4O10, Al2O3, MgOCorrect answer is option 'B'. Oxygen is highly reactive in nature. Metal oxides or hydroxides are amphoteric. However, the Al 3+ ion has high positive charge density, hence is strongly attracted to and reacts with the electron rich OH – ions present in alkalis to form aluminate ions [Al(OH) 4 –].

Register Alias and Password (Only available to students enrolled in Dr. Lavelle’s classes. Amphiprotic molecules, such as amino acids and proteins, are amphoteric. For problem 10.19, how do we know that the sulfur trioxide is acidic and that arsenic trioxide is amphoteric? Metal oxides which react with both acids as well as bases to produce salts and water are known as amphoteric oxides. community of JEE. Thank you byjus it is really a brief content . Water is the most common example, acting as a base when reacting with an acid such as hydrogen chloride: and acting as an acid when reacting with a base such as ammonia: Although an amphiprotic species must be amphoteric, the converse is not true. Postby Chem_Mod » Sun Sep 11, 2011 1:33 am, Users browsing this forum: No registered users and 0 guests. Ampholytes are amphoteric molecules that exist primarily as zwitterions over a given pH range and have both acidic groups and basic groups. The word comes from the Greek amphoteros or amphoteroi, meaning "each or both of two" and, essentially, "either acid or alkaline.". Metals react with oxygen to give basic compounds of oxygen. Amphoteric substances can react with both acids and bases (a list of the specific elements that can do this can be found on page 469 of the textbook although these elements can be easily identified for the most part by knowing that many of them coincide with the metalloids). When a substance reacts chemically, both as a base or acid it termed as an amphoteric solution. Amphoterism depends on the oxidation states of the oxide.

Amphoteric oxides are compounds of oxygen which exhibits both acidic as well as basic characteristics. Related words in acid-base chemistry are amphichromatic and amphichroic, both describing substances such as acid-base indicators which give one colour on reaction with an acid and another colour on reaction with a base.[3]. By continuing, I agree that I am at least 13 years old and have read and Neutral Oxide is one which neither has an acidic characteristic or a basic one. Which of the following oxides are acidic, Basic Amphoteric Respectively. Correct answer is option 'B'. Non-metals react with oxygen to form acidic compounds of oxides which are held together by covalent bonds. Some compounds react with oxygen to form oxides which do not exhibit acidic nor basic characteristics. The pH at which the average charge is zero is known as the molecule's isoelectric point. Why is Al 2 O 3 amphoteric? Acidity & Basicity Constants and The Conjugate Seesaw, Register Alias and Password (Only available to students enrolled in Dr. Lavelle’s classes. able to react with acid). An acidic oxide is an oxide which when combined with water gives off an acid. This topic educates with the classification of oxides based on the nature and property of compounds. EduRev is a knowledge-sharing community that depends on everyone being able to pitch in when they know something. A common example of an amphiprotic substance is the hydrogen carbonate ion, which can act as a base: Thus, it can effectively accept or donate a proton. Click hereto get an answer to your question ️ Among (a) Na2O, (b) MgO, (c) Al2O3, (d) P2O5, (e)Cl2O7 , the most basic, most acidic and amphoteric oxide can be respectively : Not all amphoteric molecules are amphiprotic.
