How many monobasic acids are there ? H 3 P O 2 , H 3 P O 3 , H 2 C O 3 , H 2 S O 4 , H 2 S 2 O 4 , H 2 C r O 4 , H 3 B O 3 , H N O 2

Correct answer

3

Step-by-step solution

Here H N O 2 , H 3 P O 2 and H 3 B O 3 are monobasic H | H − P − O − H − H − O − N = O | | O H given as H + H 3 B O 3 + H O H → [ B O H ) 4 - + H 3 O
