Question

Answer whether the below statement is true or false.
$Be{\left( {OH} \right)_2}$ is amphoteric.
If true enter 1, else enter 0.

Answer 1

Hint: We know that the compound that can possibly act both as a corrosive and as a base as per Bronsted-Lowry Theory is supposed to be amphoteric.
Example: The water particle has hydrogen iotas and, consequently, could go about as a corrosive in a response. The oxygen atom in the water atom has two solitary sets, one of which could be utilized to frame a bond with a hydrogen ion and, in this way; the water particle could go about as a base in a response. Since water can possibly act both as a corrosive and as a base, water is amphoteric.

Complete step by step solution:
We have to remember that the metal oxides which respond with the two acids just as bases to create salts and water are known as amphoteric oxides. Numerous metals, (for example, zinc, tin, lead, aluminum, and beryllium) structure amphoteric oxides or hydroxides. Amphoteric oxides likewise incorporate Lead (II) oxide, and zinc (II) oxide, among numerous others.
We must remember that the beryllium hydroxide \[Be{\left( {OH} \right)_2}\] is an amphoteric hydroxide, dissolving in the two acids and salts. With antacids, it disintegrates to shape the tetrahydroxy doberyllate (2-) anion.
For instance with sodium hydroxide arrangement, the accompanying response happens:
$2NaOH\left( {aq} \right) + Be{\left( {OH} \right)_2}\left( s \right) \to N{a_2}Be{(OH)_4}\left( {aq} \right)$
On reaction with acids salts of beryllium are formed. For instance, with sulfuric acid beryllium sulfate is formed.
$Be{\left( {OH} \right)_2} + {H_2}S{O_4} \to BeS{O_4} + 2{H_2}O$

Note:We have to know that an amphoteric oxides are mixes of oxygen which show both acidic just as fundamental qualities. These oxides while responding with corrosive goes through a balanced response to frame water and salt. This displays the essential property of the mixes. Also responds with the antacid to frame salt and water, displaying acidic property. Model: aluminum oxide.
