NaBO 2 + B 2 O 3
NaBO 2 + H 2 O 2 + H 2 O 
compound A(aq)
NaBO 2 + H 2 O 2 + H 2 O 
The compound A the sum of oxidation states of all the oxygen atoms is X. Then the value of |X| is
Text Solution
Verified by ExpertsThe correct answer is:
24
(24)
2NaBO 2 + 2H 2 O 2 + 6H 2 O 
Na 2 [(OH) 2 B(O–O) 2 B(OH) 2 ] sodium peroxoborate
X = [(–2) × 4 + (–1) × 4] = –12
Hence |X| = 12
