Q. 1 mole each of $H_{3} P O_{2}, H_{3} P O_{3}$ and $H_{3} P O_{4}$ will neutralize $x$ moles of $N a O H, y$ moles of $C a (O H)_{2}$ and $z$ mole of $A l (O H)_{3}$ (assuming all as strong electrolytes). $x, y, z$ are in the ratio of

$3 : 1.5 : 1$

$1 : 2 : 3$

$3 : 2 : 1$

$1 : 1 : 1$

$monobasic 1 H_{3} P O_{2} + x N a O H \to N a H_{2} P O_{2} + 2 H_{2} O$
$dibasic H_{3} P O_{3} + y C a (O H)_{2} \to C a H P O_{3} + 2 H_{2} O$
$tribasic H_{3} P O_{4} + z A l (O H)_{3} \to A lP O_{4} + 3 H_{2} O$
Thus, $x : y : z = 1 : 1 : 1$
