How many monobasic acids are there ?

$H_{3} P O_{2}, H_{3} P O_{3}, H_{2} C O_{3}, H_{2} S O_{4}, H_{2} S_{2} O_{4}, H_{2} C r O_{4}, H_{3} B O_{3}, H N O_{2}$

Answer:

3.00

Solution:

Here $H N O_{2}, H_{3} P O_{2}$ and $H_{3} B O_{3}$ are monobasic
$\begin{array}{l} H \\ | \\ H - P - O - H - H - O - N = O \\ | | \\ O \end{array}$
$H$ given as $H^{+}$
$H_{3} B O_{3} + H O H \to [B {(O H)_{4}]}^{-} + H_{3} O$
