# why is the boric acid is monobasic acid??

Any body can explain?

Sort by:

Boron in Boric Acid is an electron deficient atom , right ?

Actually there are many definitions of an acid . Now we must realise that Boric Acid is a Lewis acid .

When it's added to water , water acts as a Lewis Base .

Now we come to know that the H+ ion is actually not released by Boric Acid but by water.

P.S. I have to go for an exam right now . I'll provide you with the full chemical equation when I return :) · 1 year, 10 months ago

Okay I'll continue from here boric acid when added in water, breaks the H-OH bond of water and accepts the $$OH^{-}$$ ion leaving only 1 $$H^{+}$$ ion in the solution :) · 1 year, 10 months ago

Thanks Krishna $$\ddot\smile$$ .

Here's the Chemical Equation @Pritee Patel

$H_{3}BO_{3} + H_{2}O \longrightarrow B(OH)_{4}^{-} + H^{+}$

Since only one $$H^{+}$$ can be released by a water molecule, Boric Acid is a monobasic acid .

I hope I was clear $$\ddot\smile$$ · 1 year, 10 months ago
