Consider the following reactions:
$PCl_{3} + 3H_{2}O \longrightarrow A + 3HCl$
$A + H_{2}O \longrightarrow B + HCl$
Identify the number of ionisable protons present in the product $B$.

For correct statement use $T$ and for incorrect use $F$:
$(A)$ Hydrolysis of Marshall's acid gives $H_2SO_4$ and $H_2O_2$ as final products.
$(B)$ In $SCNSiH_3$ structure,the geometry around $N$ is bent.
$(C)$ The basic unit for silicates is $SiO_4^{4-}$.
$(D)$ $NH_4Cl + NaOH \to NH_3 \uparrow$.

What is meant by $Tin \ Cry$?

Among the following oxides,which one is weakly basic and yet a powerful oxidant?

Which of the following statements are correct?
$(i)$ $CCl_4$ undergoes hydrolysis easily
$(ii)$ Diamond has directional covalent bonds
$(iii)$ Fullerene is the thermodynamically most stable allotrope of carbon
$(iv)$ Glass is a man-made silicate
The correct answer is

The formation of $Al_2O_3$ involves the evolution of a large quantity of heat,which makes its use in:
