Is sodium amphoteric in nature?

– The compound $NaHC{{O}_{3}}$ is known as sodium bicarbonate is a basic compound but it can act as an amphoteric compound. – The sodium bicarbonate can react with water in two ways: one by accepting a proton from water and second by donating a proton to water.

What are examples of amphoteric oxides?

Examples of amphoteric oxides are zinc oxide and aluminium oxide.

  • ZnO(s) + 2HCl(aq) → ZnCl2(aq) + H2O(l)
  • ZnO(s) + 2NaOH(a) → Na2ZnO2(aq) + H2O(l)
  • Al2O3(s) + 6HCl(aq) → 2AlCl3(aq) + 3H2O(l)
  • Al2O3(s) + 2NaOH(aq) → 2NaAlO2(aq) + H2O(l)

Is NaOH amphoteric oxide?

Those oxides which react with both acids as well as bases are called amphoteric oxides. react With strong alkalies like NaOH to form complex salt and water e.g.

Which acids are amphoteric in nature?

Amino acids are amphoteric compounds, as they contain both acidic (COOH) and basic (NH2) groups. They can react with both alkalies and acids to form salts. In acid solution amino acids carry positive charges and hence they move towards cathode in an electric field.

Is CuO amphoteric oxide?

CuO: It is a basic oxide. Thus Cu does not give amphoteric oxide.

Which of the oxide is amphoteric oxide?

Many metals (such as zinc, tin, lead, aluminium, and beryllium) form amphoteric oxides or hydroxides. Amphoterism depends on the oxidation states of the oxide. Al2O3 is an example of an amphoteric oxide. Amphoteric oxides also include lead (II) oxide, and zinc (II) oxide, among many others.

Why are some oxides amphoteric?

An amphoteric oxide is an oxide that can act as either an acid or base in a reaction to produce a salt and water. Amphoterism depends on the oxidation states available to a chemical species. Because metals have multiple oxidation states, they form amphoteric oxides and hydroxides.

Is CuO ionic or molecular?

A metal oxide that has the formula CuO. It has an ionic structure. Copper(II) oxide or cupric oxide is an inorganic compound with the formula CuO.

Is Na2O polar or nonpolar?

Sodium oxide is an ionic compound you can chick it by yourself… A general rule of thumb for predicting the type of bond based upon electronegativity differences: If the electronegativities are equal (i.e. if the electronegativity difference is 0), the bond is non-polar covalent.

Why is zinc oxide amphoteric in nature?

because zinc oxide can reacts with both acids and bases. therefore it is an amphoteric oxide. it reacts with dilute HCL and forms zinc chloride. it reacts with Sodium Hydroxide, NaOH and form sodium Zincate.
