$ B(OH)_3 + NaOH \Rightarrow NaBO_2+Na[B(OH)_4] +H_2O.$ How can this reaction is made to proceed in forward direction.
Due to formation of chelated complex, the reaction moves in forword direction.
An element A dissolves both in acid and alkali. It is an example of
An element that dissolves both in acid and alkali is termed as amphoteric. Amphoteric substances can react with both acids and bases to form water and salts. This property is typically exhibited by elements like aluminum and zinc.
Which among the following is not a borane.
Boranes are compounds of boron and hydrogen. Common boranes include $B_2H_6$ (diborane) and $B_4H_{10}$ (tetraborane). However, $B_3H_6$ is not a known borane compound.
In Goldschmidt aluminothermic process, thermite contains
In aluminothermic process, Thermite contains 3 parts of $ Fe_2O_3$ and one part of Al.
Aluminium oxide is not reduced by chemical reactions since
Aluminium oxide is highly stable therefore it is not reduced by chemical reactions
Aluminium is not used
$ B_2H_6 $ has two types of B - H bonds.
Bauxite containing impurities of iron oxide is purified by
Bauxite containing impurities of iron oxide is purified using the Bayer’s Process. This process involves dissolving the bauxite in sodium hydroxide at high temperatures, which separates the aluminum oxide from the iron oxides.
In the purification of Bauxite by Hall’s process
The molecular formula of feldspar is
The molecular formula of feldspar is $K_2O ullet ext{Al}_2 ext{O}_3 ullet 6 ext{SiO}_2$. Feldspar is a group of rock-forming tectosilicate minerals that are important constituents of igneous rocks. The formula represents a potassium aluminum silicate composition.
Common alum is
Common alum is $K_2SO_4 ullet ext{Al}_2( ext{SO}_4)_3 ullet 24 ext{H}_2 ext{O}$. It is a double sulfate salt of potassium and aluminum, which crystallizes with 24 molecules of water. This compound is widely used in water purification, in the textile industry, and as a mordant in dyeing.
