p, q and r respectively are PH 3, PH 3, PH 3 (i) Ca 3 P 2+6 HCl arrow 3 CaCl 2+ PH 3 (ii) P 4+3 NaOH +3 H 2 O arrow PH 3+3 NaH 2 PO 2 (iii) PH 4 I + KOH arrow KI + H 2 O + PH 3

Q. Fill in the blanks :
(i) $C a_{3} P_{2} + 6 H Cl \to 3 C a C l_{2} + ..... p ....$
(ii) $P_{4} + 3 N a O H + 3 H_{2} O \to .... q ..... + 3 N a H_{2} P O_{2}$
(iii) $P H_{4} I + K O H \to K I + H_{2} O + .... r ..... .$
$p$ , $q$ and $r$ respectively are

$P H_{3}$ , $H_{3} P O_{3}$ , $P I_{3}$

$P H_{3}$ , $P H_{3}$ , $P H_{3}$

$PC l_{3}$ , $H_{3} P O_{4}$ , $P H_{3}$

$PC l_{5}$ , $P H_{3}$ , $P_{4} O_{6}$

$p, q$ and $r$ respectively are $P H_{3}, P H_{3}, P H_{3}$
(i) $C a_{3} P_{2} + 6 H Cl \to 3 C a C l_{2} + P H_{3}$
(ii) $P_{4} + 3 N a O H + 3 H_{2} O \to P H_{3} + 3 N a H_{2} P O_{2}$
(iii) $P H_{4} I + K O H \to K I + H_{2} O + P H_{3}$
